Does /Users/USER/anaconda/envs/keras/lib/libpython3.6.dylib exist? It sounds like your python install is missing important files.

Yes, it does. I did ls /Users/USER/anaconda/envs/keras/lib/libpython3.6.dylib and it showed up.

Well, beats me. Something is messed up with your python install.

I just want to update that you were right. I didn't have /Users/USER/anaconda/envs/keras/lib/libpython3.6.dylib. What I had was /Users/USER/anaconda/envs/keras/lib/libpython3.6m.dylib
I changed the filename from libpython3.6m.dylib to libpython3.6.dylib and the error went away.

That didn't work for me. I then copied my libpython3.6m.dylib file and renamed it to libpython3.6.dylib. Now I am getting this

Encountered the same problem and I'm using Python 3.5.2 with pyenv. Solve it with reinstalling my python with the following instructions. you can backup with copying your /usr/local/var/pyenv/versions/3.5.2/envs to somewhere safe and restore later.

I ran into the same problem running a conda virtual environment. I opened setup.py and changed the line (line 526) that read:
py_lib = os.path.join(get_config_var('LIBDIR'), 'libpython'+py_ver+'.dylib')
to:
py_lib = os.path.join(get_config_var('LIBDIR'), 'libpython'+py_ver+'m.dylib')
I just added the m before .dylib and now it works!

Cool. One of you guys should post a PR that checks both of these file names and uses the one that exists :)

That's not how github works. Clone a copy, modify it, submit a pull request.

big 'ol dingus here, forked, modified, and submitted

Na, no worries :)

This has been merged and resolved now in setup.py, but not in the pip install (as a note for others with the issue).
