Does conda update packages from pypi installed using pip install?

I use Anaconda (because it is awesome), and the packages available through conda install are quite extensive. However now and then I do need to install a package that isn't available in the conda repositories, and so get it from pypi instead.

My question: when I run the command conda update --all, will conda also update these pypi packages? Or do I have to update them separately? The conda docs don't seem to contain an answer to this. This question and answer seems to indicate that no, conda does not manage pypi packages, but I'm still uncertain.

Conda 4.6 has an experimental feature to enable interoperability with pip-installed packages. Use conda config --set pip_interop_enabled true. Non-conda-installed python packages that can be "managed" by conda (i.e. removed) may be updated/changed to satisfy the current solve. Manageable packages were typically installed from wheels. Sdists installed with newer versions of pip are also typically manageable. However conda won't switch out the non-conda-installed package for a conda package if the versions are equivalent.

Non-conda-installed python packages that can't be managed will anchor the environment in place until they are removed by other means. An example of unmanageable packages are "editable" installs that used pip install -e.

All of this applies to conda update --all.

This question is old, but here's a batch script that might help with automating this process on Windows. It involves going through conda list and finding packages marked with the pypi tag, which are then subsequently upgraded with pip --upgrade en masse (assuming they are out-of-date; otherwise the standard Requirement already up-to-date message will be returned).

Place the following in a batch file (e.g., condapip.bat) and try it out:

@echo off

set packages=pip install --upgrade
for /f "tokens=1" %%i in ('conda list ^| findstr /R /C:"pypi"') do (call :join %%i)
@echo on
%packages%
@echo off
goto :eof

:join
set packages=%packages% %1
goto :eof
