在conda环境中看不到pip安装的软件包

Question

I am working in a conda environment (called python36)

I have installed a package 'bctpy' while in this environment via

pip install bctpy

When I now try to import this module (while still in this environment)

import bctpy  

I receive the error:

ModuleNotFoundError: No module named 'bctpy'

When I run:

conda list 

from the command prompt the module is there, but when in python I run

help()
modules 

The outputs of which pip and which python are below:

(python36) bash-4.1$ which pip
/home/.conda/envs/python36/bin/pip
(python36) bash-4.1$ which python
/home/.conda/envs/python36/bin/python

It is not visible. is anyone able to explain what is going wrong?

Answer 1

This is a problem that one can encounter every now and then:

The PIP package is derived from the PyPI name bctpy

pip install bctpy

but the import name is derived from the top level directory name: bct/ , so it must be imported like

import bct

Answer 2

Since i could not get it after my pip install ImageHash i tried following 1. Update index in Anaconda 2. Update channel

None of them helped.

but when i went to Anaconda -> Environments tab -> Click on triangle mark next to base(root) -> Open terminal -> ran command conda install -c conda-forge imagehash

Immediately after this i was able to see the package.
