How can I find the location of packages installed by conda, like pip show?

Question

For example, when I use pip install numpy, I can use pip show numpy to get the location of numpy package.

When I install numpy by conda, e.g. conda install numpy, how can I get the location of this package?

Answer 1

You need to either

1. Open a prompt

   >>> import numpy
   >>> print(numpy.__file__)
   

2. Use a tool that will do that. I wrote "whych" for that purpose.

   python3 -m whych numpy
   

   will show the full path to the python executable that was used. You can also show the package version with

   python3 -m whych numpy --module-version
   

   (this is optional as it requires to actually import the module). The library also works within Python (useful in jupyter notebooks for instance):

   from whych import whych
   whych("numpy")
   

As you can guess, I use the second solution. It is really convenient when you work on several computers and sometimes use pip, sometimes conda, and sometimes the package manager.
