A number of posts online simply reinstalled Anaconda, any other options apart from a fresh install?
This works a charm:-
Just copy these:-
libcrypto-1_1-x64.dll
libssl-1_1-x64.dll
from D:\Anaconda3\Library\bin to D:\Anaconda3\DLLs.
Execute the following command in the cmd prompt/terminal:
conda config --set ssl_verify no
I try to create a virtual env with python 2.7 with anaconda, the base env is python 3.7. I encounter the exactly same problem. It turns out that there isn't such problem with other virtual envs with python 3.7 or 3.6.
This post works perfectly to solve my problem on win7 with anaconda prompt.
It basically says you need to add the following directories into your user environment path in windows (go to Start and type in: View Advanced System Settings, then select Environmental Variables: then select Path and click Edit: finally you can click New and add a path):
C:\your_directory_to_anaconda3\Anaconda3\Scripts
C:\your_directory_to_anaconda3\Anaconda3\
C:\your_directory_to_anaconda3\Anaconda3\Library\bin -- This is the directory for openssl
If you added conda to your PATH variables, remove it and use the "Anaconda Prompt". This solved the problem for me.
See: https://github.com/conda/conda/issues/8046#issuecomment-450582208
I faced this issue when I tried to create environment. I solved it by first activating conda base environment by using:
conda activate base
then I created the environment
conda create -n myenv python=3.7
Check the proxy URL
Verify .condarc file
For me, the problem was with the indentation in the .condarc file.
proxy_servers:
http: http://testproxy:8080
https: https://testproxy:8080
My authenticated proxy server is configured with a domain whitelist for massive and repeated downloads so root or local sudoer doesn't need to be authenticated.
Adding conda.anaconda.org is not enough as this repo redirect its traffic to amazonaws.com.
In my case, adding ".amazonaws.com" to the whitelist solved the issue.
The issue was resolved by adding a username and password to file C:\Users\xxxxx.condarc
channels:
- defaults
ssl_verify: false
proxy_servers:
http: http://xxxxx:password#sproxy.fg.abc.com:yyyy
https: https://xxxxx:password#sproxy.fg.abc.com:yyyy
I had the same problem on Windows 10-64 bit and intuitively installed the 64-bit version of miniconda. However, it results in exactly the same error above. Installing 32 bit conda installer has resolved the issue
Before installing some package (pydicom) the installation run just fine. After
it I tried to install matplotlib, but I got the same error as yours.
I tried conda config --set ssl_verify no but it didn't solve the problem so I set it again to true.
Fortunately, I had a virtual environment where I installed my packages. I closed all Anaconda prompts and tried in a new test environment. Magically, the install worked. I came back to my original virtual env and run the install again, and it worked!.
It might be that I just had to wait for some time before I could use conda install again.
One other thing I could do is remove the package that caused the problem, but I didn't have the chance to try it. If it has anything to do with some virtual environments not being affected, then one possible way to guard against this is to clone the environment before installing any new package.
Edit: I tried the same solution but It did not work. But instead of showing the error immediately, it asks me whether I want to proceed. I deactivated the env, and re-opened anaconda prompt, then did the same steps as above and worked again.
I also had the Same Issue, I resolved by installing 32 bit Anaconda Installer.
Which resolved the CondaHTTPError: HTTP 000 CONNECTION, on Windows 64 bit.
I faced this issues after "conda clean -a" on win-64.
Activating and deactivating existing conda env resolved the issue.
You might need to upgrade your openssl installation
You can download it here (Try the latest version):
https://slproweb.com/products/Win32OpenSSL.html
Source:
https://github.com/ContinuumIO/anaconda-issues/issues/6424#issuecomment-464660808
My issue was simply not running the conda init command prior to attempting to create an environment.
Came across the CondaHTTP Connection error after installing Anaconda environment on a new Windows 10 computer. I tried virtually all the recommendations above unsuccessfully! Looking up the Anaconda archives ( https://repo.continuum.io/archive/ ), I downloaded the immediate previous release .... and on installation and rebooting my PC, all is now wellscreenshot of release
In short - installing Microsoft Visual C++ Redistributable for Visual Studio solved my problem.
In more detail: upon trying a suggested solution of installing a new version of OpenSSL, the installation process told me I was missing a dependency - the Visual Studio Redistributable package. The installer led me to a direct download page of the 2017 version. I can't find that page now, but the official release of 2019 can be found here, and should work as well (found under Other Tools and Frameworks).
Uninstalling and reinstalling anaconda for all users (instead, of current user only, requires admin privileges) and activating the option to add Anaconda to PATH during the installation process, fixed the issues for me.
Thank you everyone for your responses. In my case, I found out that my Kaspersky Internet Security was blocking it the whole time. The moment I quit the application all applications were downloaded. Please check your firewall settings before trying all the above options.
I tried all of these solutions and none worked for me. After running the command
conda config --remove-key channels
in the Anaconda Prompt, everything started working for me on my next attempt.
Adding that I had the same problem on ubuntu on WSL. None of the solutions worked for me, until I realized I was working on WSL version 1 (I thought I'd already upgraded). Upgrading from WSL 1 to WSL 2 solved the problem for me.
Running following these two commands worked for me.
conda config --remove-key proxy_servers
conda clean --source-cache
I'd tried all of the advice on this and many other webpages.
In the end I broadcast a "help me Obiwan Kenobi, you're my only hope message" to a large group of people at work and one of them who used python all the time was able to help me
The trick was to set several windows environmental variables
CURL_CA_BUNDLE
REQUESTS_CA_BUNDLE
SSL_CERT_FILE
To my company's root certificate (a .cer or .crt) which I had downloaded to a spot on my disk
You may also need to add (in my case)
C:\Users\kdalbey\Anaconda3\Scripts
(or your particular \Anaconda3\Scripts) to your path.
And then I set proxies just for good measure
note I previously copied libcrypto-1_1-x64.dll, libcrypto-1_1-x64.pdb, libssl-1_1-x64.dll, libssl-1_1-x64.pdb from anaconda3\Library\bin to anaconda3\DLLs so that could be part of the secret sauce
and it didn't work until I killed and restarted anaconda-navigator
Two steps to deal with this error.
The Anaconda prompt configures the path, to include all the necessary executable files (for instance Library\bin - On Windows, launch it with admin permission). So that you need to use it to execute conda :
Update conda with conda update conda
Exit my proxy software which solved the issue.
I would like summarize some of the proposed answers in this post and propose my experience on that. As it can be understood from the error explanation, the error is related to the connection and I strongly believe that no need to uninstall and reinstall anything if the real cause of the problem be known. My problem gone away after the system powered off and powered on again one day later. So, some possible causes and their solutions (these solutions could be tested in order based on the written bulleted order) could be as follows:
Crash in anaconda prompt:
Probable solutions:
Deactivating and activating the environment, without removing all packages or …, or
Closing/reopening the prompt (Michael Heidelberg) or
Using cmd.exe instead, perhaps
Non-responsiveness of the anaconda site:
Massive site traffics related probable issues, that could be the reason of non-responsiveness or to temporary block some IPs
Probable solutions:
Retying as recommended in the error: HTTP errors are often intermittent, and a simple retry will get you on your way. It solves my problem sometimes. or
Activate or deactivate VPNs or Proxies (like use in .condarc; see: Github sroder, Nandhan Thiravia, Vinod Sangale, Peter Lucas, Sunding Wei).
Try after a while if you have time
System firewall block the site:
That might be happened by activating and deactivating of VPNs, repeatedly or by some other works
Probable solutions:
Finding the issue in system firewall and allowing the connection in the firewall settings (ScienceJedi, Github)
Reboot, perhaps
If the aforementioned ways didn't solve the problem, testing the related answers in the following order:
Add ...\Anaconda3\Scripts, ...\Anaconda3\, and ...\Anaconda3\Library\bin to the path (talentcat, skerjj, Victor Ochieng, jankap), perhaps need a reboot after (lightarrow)
Copying libcrypto-1_1-x64.dll and libssl-1_1-x64.dll from D:\Anaconda3\Library\bin into D:\Anaconda3\DLLs (Swapnil)
I think it could be used in the first step because It is unlikely to be cause of any other problem. The reason I didn't mention this at the beginning is that the developers could placed these files in that directory during installation, too, in default, but they didn't; perhaps it had some reasons (Github).
Note: these files are for Python >3, and I didn't find them for Python 2. Perhaps they have another names.
It must be said that my problem didn't solve by this solution.
Keep your SSL stack up-to-date (kamal dua, Anaconda troubleshooting, update openssl, Abdulrahman Bres, Update to openssl 1.1.1)
I didn't recommend it at first because Its not a good idea to unset ssl verification unless you know what you are doing (Pratyush comment) and somewhere I read that it couldn't return to True again.
It must be said that my problem didn't solve by this solution, too.
conda config --set ssl_verify false
conda update openssl ca-certificates certifi
I'm an undergraduate research assistant working on a Linux server without root privilege. I'm trying to install the Rstudio server but the Rstudio website only provides the installation method for sudoers. Is it possible to install it without root access? I'm asking because I'm really not sure if I could get access from the manager. Any help will be appreciated!
No, you can't install it without root access. But there are a couple of things you could do to piece together a solution. Here are two options:
Extract the server and run it directly
You have to be root to install packages, so you can't install the .deb/.rpm file yourself. However, you could extract the contents of the file to a directory inside your home directory and run RStudio Server from there, by executing the rserver program in a regular shell.
Note that this will probably require an afternoon of editing the rserver.conf file to tell it where to find the rest of the files in the installation (since it presumes they are installed in /usr/lib by default). You can get some inspiration for how to do this here: https://github.com/rstudio/rstudio/blob/master/src/cpp/conf/rserver-dev.conf
Run the desktop version and forward the graphics
The other route is to run RStudio Desktop on the server; we make several builds of RStudio Desktop that are installer-less and can just be unpacked into your home directory. Then run an X11 server on your own computer and an X11 client on the RStudio server, so that the RStudio Desktop instance appears on your computer instead of the server.
Yes, you can run rserver without root priveliges.
For RStudio 1.4 I patched the following line into src/cpp/core/LogOptions.cpp
const FilePath kDefaultLogPath = core::system::xdg::userDataDir().completePath("log");
Then you need to set the system environment variables to some location read-writeable for the user, like
RSTUDIO_CONFIG_DIR=$HOME/.config/rstudio
RSTUDIO_CONFIG_HOME=$HOME/.config/rstudio
RSTUDIO_DATA_HOME=$HOME/.local/share/rstudio
And start rserver with the option
--server-data-dir={directory writeable for user}
--server-pid-file={file-path creatable for user}
--database-config-file={config-file}
With these adjustments it runs for me when I start it as a simple user (no root privileges) with
rserver --auth-none=1 --www-frame-origin=same --www-port={port} --www-verify-user-agent=0 --server-data-dir={my-tmp-path} --server-pid-file={my-tmp-path}/rstudio.pid --database-config-file={my-tmp-path}/db.conf}
ATTENTION:
But be aware, that anyone who can reach your system and the specified port from the network has access to the running RStudio in his browser and therefore can run any command in the name of the user on your system now.
I have installed Anaconda 3 on Windows 10 64-bit. The installation completed successfully. I could start idle.exe and it works. I can start the Anaconda Powershell and Anaconda Prompt, but I cannot start the Navigator nor Spyer or Jupyter. Launching them from the start menu will bring up the Windows shell windows for a moment, before they disappear and nothing happens.
I have tried starting the navigator from the Anaconda Prompt and this is what the error message looks like:

I have searched the internet for root causes of the last line in the error message with no success. There are a few tips how to fix it, but nothing worked.
The exact version I have installed is Anaconda3-2019.10-Windows-x86_64.exe.
I have tried uninstalling and reinstalling Anaconda in all different "flavors":
for all users, without adding the path to the environment variables
for all users, with adding the path to the environment variables for
current user, without adding the path to the environment variables
for current user, with adding the path to the environment variables
Anaconda is installed into a directory without spaces in its name and no fancy characters: c:\users\frank\Anaconda3.
I have removed .anaconda and tried launching the navigator, spyer and jupyter again with no success.
Spyer comes up with a message that it had crashed during the last session. I followed the advice and deleted the .spyder-py3 folder, but no change.
How can I find more information about the reason for the problem on my system? Are there any log files that contain more information? I checked if HTTPSHandler is defined where Anaconda would search for it (please consider my limited expertise in Anaconda, when assuming where to look for resources...).
I installed the same Anaconda3 version on another computer and it works right from the start.
After reading another suggestion about updating conda using conda update conda and trying it on the Anaconda prompt I received the following error:
(base) PS C:\Users\Frank> conda update conda

I had the idea that SSL could be a problem and uninstalled OpenSSL v1.1.0g (Win64), then checked again. That doesn't help. Installing OpenSSL v1.1.0g (Win64) again doesn't make a difference either. On the other hand I would have assumed that Anaconda brings all components and modules it needs.
Any ideas how to continue troubleshooting?
I kept digging for answers and came across a discussion at GitHub:
CondaHTTPError: Caused by SSLError("Can't connect to HTTPS URL because the SSL module is not available)
I followed the advice, uninstalled my OpenSSL version and installed the latest one from the page https://slproweb.com/products/Win32OpenSSL.html. This is now "Win64 OpenSSL v1.1.1d" and right after the installation all the issues with Anaconda were gone. I can use conda to update, the Anaconda Navigator comes up, Jupyter Notebook works. All is fine.
I gave the following command
library(reticulate)
py_install("pandas")
I am getting an error while installing python packages in RStudio :

If somehow your openssl is an old version (as discussed here: https://github.com/conda/conda/issues/8046), you can install an up-to-date version following the guides below:
https://jchornsey.wordpress.com/2015/03/17/installing-openssl-in-windows-8-1/
https://www.cloudinsidr.com/content/how-to-install-the-most-recent-version-of-openssl-on-windows-10-in-64-bit/
As these guides explain, "the official OpenSSL website offers Linux sources only." For Windows binaries, you can obtain from https://slproweb.com/products/Win32OpenSSL.html provided by Shining Light Productions. The github issue discussion mentions that this link is listed on the OpenSSL wiki (https://wiki.openssl.org/index.php/Binaries -- I went there two days ago to confirm but today that page does not load, perhaps due to the Easter holidays).
The guides also explain that "If you’re not developing software, you don’t need the full versions; the “Light” version is intended for end-users.
Installing Python from RStudio seems interesting. One way to go is use reticulatepackage in R which provides R interface to Python and use Python within R.
Python packages are generally installed either using pip or 'conda' if anaconda is being used.
Then to use it in R, mention the proper path where python is installed in the system.
library(reticulate)
use_python("/usr/local/bin/python")
Reticulate also provides a way to install package using py_install() function.
library(reticulate)
py_install("pandas")
Please look for more details about reticulatepackage here and about installing packages here.
I'm trying to make julia language available through jupyterhub on an ubuntu server.
I already have installed and configured the jupyterhub. Its working fine with python3.5.
And the authentication method is Regular Unix users and PAM.
I installed the julia language in /usr/local/julia-1.0.2/ and it is available for all users globally.
then with the root user I set the JULIA_DEPOT_PATH="/usr/share/juliapackages/
then again with the root user, I run the julia and run the
using Pkg
Pkg.add("IJulia")
it installs the IJulia in the specified path.
from this point, I didn't find any further useful instructions on the internet over the subject of installing julia kernel for jupyterhub, so I don't know how to proceed.
does anybody have a good step by step document to find the solution?
I followed the instruction proposed here but it seems doesn't work for me.
As you are using Jupyterhub, the best way would be to use a docker spawner and use the data science docker image which has Julia already installed and configured.
