conda command not found
I recently installed oh-my-zsh to avoid my mistakes I have been constantly making while using git and improve my command line interface experience.
oh-my-zsh was great but It suddenly started not recognizing conda command.
Naturally, I got a problem with using conda virtual environment.
Add Path to ~/.zshrc file
It seems like this new theme in zsh does not have path to conda so does not know where to look when conda command comes. As suggested here, I found the right path from .bash_profile and pasted it to .zshrc file.
So first, open your .bash_profile file by running following command.
You will see the PATH automatically added by Miniconda in my case. If you installed Anaconda, you will see Anaconda instead. Copy this two lines.
# added by Miniconda3 installer
Go back to the terminal and open .zshrc file via vim and paste the above lines somewhere.
source the file or open a new terminal to make the change in effect.
Now zsh understands conda command!
While using new Python 2 Kernel for Jupyter Notebook installed last time (Previous post), I found I cannot use Python libraries I had in my Python 2 in my local. Apparently, Python 2 environment used in the new Python 2 Kernel was not the same Python 2 environment that I have been using so far.
To resolve this issue and avoid confusion, I separated python environments using Conda and tie a specific environment to each Jupyter Kernel.
The first step is obviously creating a python environment (Later I will explain how I did it but here is the basic tutorial for this). But unfortunately, running Jupyter notebook from an environment does not mean the notebook will run in the same environment. It uses the default Conda environment instead of specific environment you are running the notebook from.
I had to install nb_conda, which is an extension to provide Conda environment and an access to the associated packages from within Jupyter (Ref). Detailed info can be found here on GitHub.
This is how you install nb_conda.
$ source activate py2
(py2) $ conda install nb_conda
Checking Kernel from Jupyter
Run Jupyter Notebook after activating your environment. You can see now your Conda environment can be found in the kernel list. You can also check which kernel you are running the current notebook with from the top right.
(py2) $ Jupyter notebook
