Can't import module after install [Anaconda] about pangolin HOT 7 CLOSED

The module isn't there. If you go to lib/python/site-packages/ I suspect you will not find that module in there.

So your setup/install failed, maybe because of a missing dependency. Read the documentation, make sure you install all the dependencies and run setup install again. There has to be a dependency missing somewhere.

Edit:
I just noticed that it installed it to your '/home/user/anaconda3/lib/python3.5/site-packages' directory.
If you're using a virtual environment, maybe it is coping the module to the wrong directory?

Hi, thanks for your quick response!

Turns out I 'ignored' the warning below. I did not actually ignored it, I ran python -m pip install pybind11 to install the dependency, but this did not remove the warning so I proceeded anyway. Also it says in the readme that pybind11 is not required to be installed.

Just now I found this issue where someone said to install it using a specific pip. That didn't help, but as I'm using Anaconda I ran conda install pybind11, after which the warning disappeared.

So I rechecked all the dependencies and I think I have all of them installed.

Also the library seems to be installed in the right place. But still does not import.

Hmm, if the module is in the right path you shouldn't get that import error. Have you tried installing another module to that environment and checked to see if it imports correctly?

from pangolin.

Yes, I am able to use other projects that have more complete installers.

I seem to have located the problem. The library that is build is for python 3.6, which is my system python, and then copied to my (python 3.5) Anaconda environment.

Maybe I need to pass the location of my python binary to the CMake script...

If that's the case, see the Closed issue #11, that may help you. And then you should probably close this issue as well.

Thanks @plasticuproject!
