Check if you have Conda installed
% conda update --all -y
>> command not found: conda
Install Anaconda Python
I prefer an installer on my laptop:
After installation, make sure you restart the Terminal (control N).
Note, Anaconda includes the following and much more:
curl
numpy
matplotlib
jupyter_core
protobuf
sqlite
ipython
jupyterlab
jupyter
notebook
matplotlib
pip
pandas
pillow
scikit-learn
python-3.9
Update Conda
$ conda activate base$ conda update -n base -c defaults conda$ conda update --all -y
How to start Jupyter Notebook
cd $REPO // the directory you want as a base of your project (e.g. in GitHub directory)
jupyter-lab
This will start in the browser: http://localhost:8888/lab
That is all you need to start working.
Alternatively, you may want to create ENVIRONMENT specific installation. This is useful if you work on multiple projects, especially over a long time when LIBRARIES change and code becomes outdated.
Check Python Version that came with Conda
% python --version
Python 3.9.13
Create a Conda TensorFlow environment
$ conda create -n py_39_tf python=3.9 tensorflow -y
This installs tensorflow pkgs/main/osx-64::tensorflow-2.9.1
List conda environments you already created
$ conda info --envs
% conda info --envs
# conda environments:
#
base * /Users/uki/opt/anaconda3
py_39_tf /Users/uki/opt/anaconda3/envs/py_39_tf
Activate the Conda Environment you want Jupyter in.
% conda activate py_39_tf
(py_39_tf) uki ~ %
Install new Jupyther kernel
$ python -m ipykernel install --user --name py_36_tf --display-name "Python 3.6 (tensorflow)"

Installed kernelspec py_36_tf in /Users/uki/Library/Jupyter/kernels/py_36_tf
Refresh a page with Jupyther Lab notebook and change to the new kernel.
Delete kernels that you want to replace
$ rm -r ~/Library/Jupyter/kernels/my_old_kernel_name
