I'm working in a mac(apple m1).
I used M-x pythonic-activate RET /path/to/virtualenv RET to change the virtual environment in anaconda-mode. But Python Shell, pdb and flycheck use three different environments.

It works fine when I used C-c C-p, in a Python Shell.

>>> import sys
>>> print(sys.path)
['', '/Users/felix/miniforge3/envs/gluon/lib/python38.zip', '/Users/felix/miniforge3/envs/gluon/lib/python3.8', '/Users/felix/miniforge3/envs/gluon/lib/python3.8/lib-dynload', '/Users/felix/miniforge3/envs/gluon/lib/python3.8/site-packages']

But the pdb( python -m pdb test.py) use the python2.7 from the system.

 ['', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python27.zip', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-darwin', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac/lib-scriptpackages', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-tk', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-old', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload', '/Library/Python/2.7/site-packages', '/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python', '/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/PyObjC']

While the flycheck use python from homebrew.

Syntax checkers for buffer test.py in python-mode:

First checker to run:

  python-pycompile
    - may enable:    yes
    - executable:    Found at /opt/homebrew/bin/python3
    - next checkers: python-mypy

Checkers that are compatible with this mode, but will not run until properly configured:

  python-flake8 (automatically disabled) reset
    - may enable:         no
    - executable:         Found at /opt/homebrew/bin/python3
    - configuration file: Not found

    - next checkers:      python-pylint, python-mypy

Flycheck Mode is enabled.  Use C-u C-c ! x to enable disabled
checkers.

I tried pyvenv, and it works.
I add (require-package 'pyvenv) into init-local.el.
Use M-x pyvenv-activate to specify the virtual environment directory. After that, Python Shell, pdb and flycheck use the same environment.

Maybe It is batter to add pyvenv into default configuration.

Thanks for filing this. I don't think I want to prescribe how people should manage their python virtual envs, and locally I use poetry, nix and direnv instead of pyvenv etc.

You're right, this is more like a special use case. Just record it in case others encounter the same problem.

I've updated the note in init-python.el at least. :-)
