Some problems with installing JupyterLab - jupyter-notebook

Installed JupiterLab, but ran into a problem in the terminal.
> Terminals not available (error was No module named 'winpty.cywinpty')
Tried the following commands:
First
pip install pywinpty
Requirement already satisfied: pywinpty in c:\python38\lib\site-packages (0.5.7)
Second (version)
Python --version 3.8.3
jupyter-lab --version
2.1.5
ipython --version
7.16.1
Third
import winpty
conda install pywinpty
and others don't get rid of startup errors

On Windows it can be solved by installing pywinpty from the wheel provided here: https://www.lfd.uci.edu/~gohlke/pythonlibs/ .
Just download (the wheel) and install it via:
pip install -I the_wheel_name_you_have_downloaded

I can't install lableImg Annotation tool in M1 Mac

While installing LabelImg in M1 Mac using below command
pip install pyqt5 lxml
This is the error I got
ERROR: pyqt5 from https://files.pythonhosted.org/packages/7c/5b/e760ec4f868cb77cee45b4554bf15d3fe6972176e89c4e3faac941213694/PyQt5-5.14.0.tar.gz#sha256=0145a6b7de15756366decb736c349a0cb510d706c83fda5b8cd9e0557bc1da72 has a pyproject.toml file that does not comply with PEP 518: 'build-system.requires' contains an invalid requirement: 'sip >=5.0.1 <6'
How to install lableImg annotation tool in M1 Mac?
I got it to work by using the following commands
brew install pyqt#5
pip install labelimg
And that's it, it just works
You just need to type labelimg in the Terminal and the app will start running
I don't know why they don't tell you this in the installation guide
Alrighty!
On MacOS Monterey, none of the other solutions posted here solved this problem for me. However, I managed to easily solve the issue, without a virtual environment or too much fiddling about like so:
Firstly, you have to download all labelImg packages from this link:
https://github.com/tzutalin/labelImg#macos
(You can download it as a .zip file or clone it)
Unzip and then in your terminal cd into whatever directory you downloaded the above files to.
Then run the following commands in order:
pyrcc5 -o libs/resources.py resources.qrc
Then,
pip3 install lxml
Finally,
python3 labelImg.py
It should run without an issue now.
You can go one of two ways:
Using brew:
You can use homebrew to install the dependencies - like qt and libxml2. This will let your package manager handle everything and generally should solve the problem with the . Then you can run
python3 labelimg.py
Using Virtual Environments:
This is the more recommended way to go about in such cases. You can use conda, pipenv or venv to create a virtual environment which is isolated from your system python installation. Then you can try to install it as explained in the README.rst in the root of the repository:
brew install python3
pip3 install pipenv
pipenv run pip install pyqt5==5.12.1 lxml
pipenv run make qt5py3
pipenv run python3 labelImg.py
[Optional] rm -rf build dist; python setup.py py2app -A;mv "dist/labelImg.app" /Applications
You can try the two methods and and get back with the errors if there are any.
This is my note.
I just succeed on my Mac M1 Chip
CHECK THIS OUT!
Installation of labelimg on mac m1 chip
my first reference
my second reference
First, you must use terminal with rosetta version
Then, you already have python3
Then...
[Done]
# check where python3 is
$ where python3
# create env
$ /usr/bin/python3 -m venv env
# check env is
$ where env
# activate env list
$ source env/bin/activate
# updated to the newest
$ pip install --upgrade pip
# installation of PyQt5
$ pip install PyQt5
# start to run labelImg.py
$ cd Documents/repos/labelImg
$ pip3 install pyqt5 lxml
$ make qt5py3
# [run ok!!]
$ python3 labelImg.py
Using Conda
Create a virtual environment in conda and activate it
conda create -n venv
conda activate venv
Install pyqt using conda
conda install pyqt
Install lxml using pip
pip install lxml
Change directory to the downloaded/cloned labelImg folder
cd path/to/labelImg/folder/
Make qt5py3
make qt5py3
Run LabelImg
python labelImg.py

Jupyter lab 2.2.9
Windows 10
Update-not working in Version 2.2.6
I meet this problem after reset my laptop.
First, JupyterLab 2.2.x requires NodeJS to be installed.
Then maybe you can try this way:
pip install "jupyter-kite<2.0.0"
jupyter labextension install "#kiteco/jupyterlab-kite"
In my opinion, pip install jupyter-kite will install the latest version of jupyter-kite but the version of jupyter-kite should less than 2.0.0 if user use JupyterLab 2.2.x
The code comes from The GitHub page of Jupyterlab-kite.

Trying to install Tensorflow-Probability using reticulate - how to specify user?

In order to install the greta package, I need to first install tensorflow-probability. Tensorflow and Python 3.7 Anaconda are already installed.
When I attempt the following command in R: reticulate::conda_install("r-tensorflow", "tensorflow-probability", pip = TRUE), I get the following:
Could not install packages due to an EnvironmentError: [WinError 5] Access is denied:
'C:\\Users\\PHILTE~1\\ANACON~1\\envs\\r-tensorflow\\Lib\\site-packages\\numpy\\core\\multiarray.cp36-win_amd64.pyd'
Consider using the `--user` option or check the permissions.
I have admin permissions on my laptop, so I'm unsure why I'm getting an access denied. But how do I add the --user command within the reticulate command?
This webpage fixed it all for me: http://preposterior.updog.co/november-8-2018-getting-your-computing-environment-ready-for-greta.html#november-8-2018-getting-your-computing-environment-ready-for-greta
Steps:
Install Anaconda
Open Anaconda Prompt and run the following:
conda activate r-tensorflow
pip install --no-dependencies tensorflow-probability==0.4.0
conda install tensorflow=1.11
pip install h5py pyyaml requests Pillow scipy
Back in R, install the greta package from CRAN.
From version 0.4.0, greta now includes a install_greta_deps() function that installs all the relevant python modules required for greta.

Error while install airflow: By default one of Airflow's dependencies installs a GPL

Getting the following error after running pip install airflow[postgres] command:
> raise RuntimeError("By default one of Airflow's dependencies installs
> a GPL "
>
> RuntimeError: By default one of Airflow's dependencies installs a GPL
> dependency (unidecode). To avoid this dependency set
> SLUGIFY_USES_TEXT_UNIDECODE=yes in your environment when you install
> or upgrade Airflow. To force installing the GPL version set
> AIRFLOW_GPL_UNIDECODE
I am trying to install in Debian 9
Try the following:
export AIRFLOW_GPL_UNIDECODE=yes
OR
export SLUGIFY_USES_TEXT_UNIDECODE=yes
Using export makes the environment variable available to all the subprocesses.
Also, make sure you are using pip install apache-airflow[postgres] and not pip install airflow[postgres]
Which should you use: if using AIRFLOW_GPL_UNIDECODE, airflow will install a dependency that is under GPL license, which means you won't be able to distribute your resulting application commercially. If that's a problem for you, go for SLUGIFY_USES_TEXT_UNIDECODE.
If you are installing using sudo run one of these commands:
sudo AIRFLOW_GPL_UNIDECODE=yes pip3 install apache-airflow
OR
sudo SLUGIFY_USES_TEXT_UNIDECODE=yes pip3 install apache-airflow
NOTE: If pip3 (python3) does not work for you, try pip command.
The pip command can be pointing to python2 or python3 installation depending on your system. Verify this by running pip --version.
Windows users can use the command below before installing apache-airflow:
$ set AIRFLOW_GPL_UNIDECODE=yes
then
$ pip install apache-airflow
In case you are installing the airflow on Windows and through Python terminal then you need to write this:
Set SLUGIFY_USES_TEXT_UNIDECODE=yes
pip install apache-airflow[postgres]
It worked with me after I struggled with trying many other options. Hope this will work with you too.
Below command should install apache-airflow and lets you pull changes into PyCharm for building DAGs and coding for Airflow.
SLUGIFY_USES_TEXT_UNIDECODE=yes
pip install apache-airflow
Also, if you are installing using sudo you can use:
export AIRFLOW_GPL_UNIDECODE='yes'
sudo -E pip3 install apache-airflow
(or use SLUGIFY_USES_TEXT_UNIDECODE)
Run the following command in your python terminal: SLUGIFY_USES_TEXT_UNIDECODE=yes pip install apache-airflow==1.10.0
Use below command to install apache-airflow
sudo SLUGIFY_USES_TEXT_UNIDECODE=yes \
pip install apache-airflow[async,devel,celery,crypto,druid,gcp_api,jdbc,hdfs,hive,kerberos,ldap,password,postgres,qds,rabbitmq,s3,samba,slack]
