I am trying to load jupyter notebook with PyPy. I have done it already on different machines and I never got any problem. This time, however, (on an iMac with OSX 10.11.16) I am getting the following error message:
This is the script I use to load the notebook with PyPy:
import re
import sys
from IPython import start_ipython
if __name__ == '__main__':
sys.argv[0] = re.sub(r'(-script\.pyw|\.exe)?$', '', sys.argv[0])
sys.exit(start_ipython())
I run it from bash: pypy script.py notebook
If I run it without notebook, the IPython session starts as it is supposed to, so the issue must be related to the notebook but I can figure it out. Of course, zeromq is installed, but I have no idea what headers in the error message refers to... Any clue on how to solve this?
P.S. I have used pypy -m pip install jupyter to install it.
"zeromq headers" means what is necessary for developing with, as opposed to only using, the zeromq library. It may be in some "zeromq-dev" package or similar, depending on what distribution system you use on your OS/X.
Normally you'd get such an error when trying to do pip install, but in this case, "zmq" is written using the old CFFI style, deprecated since 2015; as a result it requires the headers at run-time.

I am trying to open a Jupyter Notebook file in classic Jupyter Notebook interface. I am attempting to create an interective app that uses Julia programming language in interactive codes. For that I am trying to use the Interact library, because I know it features things such as buttons, sliders, etc. It requires the WebIo extension to be installed. However, from what I have experienced so far, Jupyter notebook does not detect the WebIO extension.
I tried following the instructions at https://juliagizmos.github.io/WebIO.jl/stable/gettingstarted/ and at https://juliagizmos.github.io/WebIO.jl/stable/troubleshooting/not-detected/. In the last link I found that another extension needed to be install and I found more information in this link (https://juliagizmos.github.io/WebIO.jl/latest/providers/ijulia/). I tried executing this command in my Windows prompt and it had apperently been succesful. When executing the command suggested at the second link, I got an error in the Julia REPL saying that WebIO extension for Jupyter Lab must be installed through Python or Conda, which I had already done.
I am also a bit confused as to how I can check to see if the extension is enabled.
I believe the problem has to do either with the installation of IJulia or the pip installation of WebIO. I rarely use pip, so I don't know if I did it correctly.
Thank you.
I am trying to create a layer of simple-salesforce (Python Library) in AWS lambda, and trying to use it (import it) from my python code. I am having windows machine.
Though I read that there might be issues due to compilation windows so I install ubuntu1804 from windows store and then went ahead with creating zip for lambda layers. (zip is created for python folder with structure "python/lib/python3.6/site-packages/......")
I am using Python 3.6. I went through few articles for this issue but could find any resolution. this Video helped me creating a layer for Pandas & requests in AWS successfully with minor tweaks in pip commands I used
sudo python3 -m pip install simple-salesforce -t build/python/lib/python3.6/site-packages
Exactly same process i used for Simple salesforce and I am getting below error is as below:
Unable to import module 'lambda_function': /lib64/libc.so.6: version `GLIBC_2.18' not found (required by /opt/python/lib/python3.6/site-packages/cryptography/hazmat/bindings/_rust.abi3.so)
Edit: --
Another approach I tried using .whl though this was not giving above error but giving error as "request module not found" and when I add request module layer it gives error authlib not found. (request layers work fine if I comment salesforce related things. Even tried uploading as simple layer same authlib issue I got)
Edit :
Lambda code I am using is as below
the code I am using is basic code which doesnt have any logic with empty imports
import json
import pandas as pd
import requests as req
from simple_salesforce.format import format_soql
def lambda_handler(event, context):
#TODO
I also received the same error while installing pysftp on lambda which uses cryptography library(python)
the error was similiar to (required by /opt/python/lib/python3.6/site-packages/cryptography/hazmat/bindings/_rust.abi3.so)
The solution that worked for me is
1] pip uninstall cryptography
2] pip install cryptography==3.4.8
The following github link explains it in detail
https://github.com/pyca/cryptography/issues/6390
AWS lambda functions are like virtual environments, they do not come with the .so files which are kernel level packages. When installing the python packages you have to make sure the system dependent files are installed with it. This can be achieved by passing the argument --platform to pip install.
From AWS post How do I add Python packages with compiled binaries to my deployment package and make the package compatible with Lambda?:
To create a Lambda deployment package or layer that's compatible with Lambda Python runtimes when using pip outside of Linux operating system, run the pip install command with manylinux2014 as the value for the --platform parameter.
pip install \
--platform manylinux2014_x86_64 \
--target=my-lambda-function \
--implementation cp \
--python 3.9 \
--only-binary=:all: --upgrade \
simple-salesforce
I changed my code to not use simple_salesforce library and work out all the logic with Requests ( using Salesforce REST APIs).
This is not really ideal but I could get it working as I had some deliveries to meet.
I am trying to make run a script for webscraping. However, I feel the problem could be that I keep running the written script in the wrong console.
So far I could not really understand the differences between the consoles cmd and Anaconda Prompt. Anaconda Navigator looks rather like an administrative tool, but it seems still to make a difference for my code whether I use a terminal from there or not. Could anyone elaborate on that?
Much appreciated
cmd: command-prompt, that used to run our python script, especially for scripts with .py extension. Besides that, we can used to install python library
Anaconda Prompt: almost similar to cmd. But usually we used to open jupyter notebook or other console on Anaconda Navigator.
Anaconda Navigator: a GUI desktop application that is included in the Anaconda installation package. Through Anaconda Navigator, programmers can easily run and manage Conda packages, environments and channels without the need to use command prompt commands. Anaconda Navigator can search for packages in the anaconda cloud repository.
So, the difference depends on what we want to do. You can't judge the problem arises because of the wrong console. It depends on the error message that appears.
Suggestion: read the error message, and analyze or find a way to solve the problem
I am trying to install the pyperclip module for Python 3.6 on Windows (32 bit). I have looked at various documentations (Python documentation, pypi.python.org and online courses) and they all said the same thing.
1) Install and update pip
I downloaded get-pip.py from python.org and it ran immediately, so pip should be updated.
2) Use the command python -m pip install SomePackage
Okay here is where I'm having issues. Everywhere says to run this in the command line, or doesn't specify a place to run it.
I ran this in the command prompt: python -m pip install pyperclip. But I got the error message "'python' is not recognized as an internal or external command, operable program or batch file.
If I run it in Python 3.6, it says pip is an invalid syntax. Running it in IDLE gives me the same message.
I have no idea where else to run it. I have the pyperclip module in my python folder. It looks like a really simple problem, but I have been stuck on this for ages!
You need to add the location of the python.exe to your $PATH variable. This depends on your installation location. In my case it is C:\Anaconda3. The default is C:\Python as far as I know.
To edit your path variable you can do the following thing. Go to your Control Panel then search for system. You should see something like: "Edit the system environment variables". Click on this and then click on environment variables in the panel that opened. There you have a list of system variables. You should now look for the Path variable. Now click edit and add the Python path at the end. Make sure that you added a semicolon before adding the path to not mess with your previous configuration.
I am running ipython notebook on my OSX machine and/or my ubuntu 14.04 machine. I am using ipython 3.0.0, and ipython (jupyter) notebooks.
When I start an ipython notebook, under New there is a terminal option, but it's unavailable for me.
I haven't been able to find any documentation on this feature, how to activate it or what it does.
The ipython notebook --help command doesn't mention it and I haven't found anything in the documentation either.
I haven't discovered the special keywords to search google for to get any information either.
What does this feature do? How do I activate it? Is there any documentation on this available?
IPython/Jupyter appears to support browser-based interactive terminal sessions. This is enabled on my machine by installing the terminado package with pip or conda. This fixes the "Terminals Unavailable" message on the drop-down, and lets me start up a (bash) terminal session in a new tab.
See this commit:
IPython on GitHub
Here's the code in Lib/site-packages/IPython/html/notebookapp.py responsible for this item (located the file by searching the source for "Terminals" case-sensitively):
def init_terminals(self):
try:
from .terminal import initialize
initialize(self.web_app)
self.web_app.settings['terminals_available'] = True
except ImportError as e:
log = self.log.debug if sys.platform == 'win32' else self.log.warn
log("Terminals not available (error was %s)", e)
As you can see, there should be a message in the console log specifying what went wrong (you may need to increase log verbosity with ipython notebook --log-level=<level> to see it). In my case, it said:
Terminals not available (error was No module named fcntl)
The html.terminal module that is being imported appears to provide a web-based IPython interactive console.
Support for Windows terminals with terminado dependency was added in Jupyter 5.3.0:
https://github.com/jupyter/notebook/pull/3087
Actually it's jupyter notebook 5.3.0, not jupyter. the two versions is not the same thing.
- jupyter --version
- jupyter notebook --version
I ever suffered from this.
