Use Conda environment in pycharm

Question

Conda env is activated using source activate env_name.

How can I activate the environment in pycharm ?

Answer 1

I had the same problem i am on windows 10 professional 64 bit my solution was to start Pycharm as adminstrator and it worked

Answer 2

How about environment.yml

Pycharm can create a new conda environment indeed. Unfortunately, until this issue is fixed, it won't offer environment.yml support, which means it won't install the dependencies declared there.

When working on a project based on such a file, you need to create / update the dedicated env manually on your machine:

conda env create -n <my-project>

Then remember to update each time environment.yml changes (from you or upstream).

conda env update -n <my-project>

Not ideal

Answer 3

The best PyCharm specific answer is this one by wasabi (below).

In general though, if you want to use an interpreter from within a Conda environment then you can change the location of the interpreter to point to the particular environment that you want to use e.g. /home/username/miniconda/envs/bunnies as mentioned in this comment.

However, as mentioned in this answer by Mark Turner, it is possible to have a shell script executed when activating an environment. This method will not run that shell script, but you can follow his workaround if you need that shell script run:

• open a conda prompt
• activate the environment
• run pycharm from the conda prompt

Answer 4

It seems important to me to know, that setting project interpreter as described in wasabi's comment does not actually activate the conda environment.

I had issue with running xgboost (that I installed with conda) inside PyCharm and it turned out that it also need some folders added to PATH. In the end I had to make do with an ugly workaround:

1. Find out what are the additional folders in PATH for given environment (with echo %PATH% in cmd)

2. In the file I wish to run put to the top before anything else:

import os os.environ["PATH"] += os.pathsep + os.pathsep.join(my_extra_folders_list)

I know this is not at all proper solution, but i was unable to find any other beside what Mark Turner mentioned in his comment.

Answer 5

As mentioned in one of the comments above, activating an environment can run scripts that perform other actions such as setting environment variables. I have worked in one environment that did this. What worked in this scenario was to:

• open a conda prompt
• activate the environment
• run pycharm from the conda prompt

Pycharm then had access to the environment variables that were set by activating the environment.

Answer 6

open

pycharm/preferences/project/Project Interpreter

And check existing interpreter. Conda environments may already be listed there.

If not exists, you can create a new conda environment with "Create Conda Env" button

If you are looking for a specific conda environment you can use 'add local'. When you click 'add local' you will input conda environment path + /bin/python

You can list all conda environment in your system with following commnad.

>>conda info --env
# conda environments:
#
tensorflow            *  /Users/username/miniconda3/envs/tensorflow

you can chose the approach best fits your needs.
