Using virtualenv on Jupyter Notebook

Question

I trying to use virtualenv on jupyter notebook, to use all packages installed in an environment, but inside jupyter they are not recognized.

Already tried:

pip install tornado==4.5.3
pip install ipykernel==4.8.2

What I do is: Initializing the environment on prompt (windows 7): Move to directory of environment: cd C:\Python\Envs\env1\Scripts and use: activate now the promt show (env1), so it's active.

From there, I move to another directory and call jupyter, but when starts, the package installed on envoriment are not callable.

How we can active the environment on jupyter?

for Mac OS/Linux users:

python -m venv venv
source venv/bin/activate
pip install jupyter
ipython kernel install --user --name=venv
jupyter notebook

Maybe you should install an ipykernel inside your venv first.

virtualenv .venv
.venv\Scripts\activate.bat to activate the venv.
python -m pip install ipykernel
python -m ipykernel install --user --name .venv to install a new kernel named .venv.
jupyter notebook here and you can select your new kernel.

REFERENCE: Kernels for different environments

I had to use python -m ipykernel instead of ipykernel from the command line.

@rudolfbyker That's fine. Adding a python -m prefix will be safer.

No, I mean ipykernel was not found on the path, even when the venv is activated.

The reference documentation mentioned suggests python -m ipykernel, there are no mentions of ipykernel as a shell command (anymore?).

I found that I had to exit the venv and re-activate it before it would use the local version of jupyter instead of the global one.
