net.predict() Raises Error Calculating Dot Product; Theano Cannot Find MKL Lib

[tylerpayne]

I am trying to use theanets to take advantage of its favorable speed in order to replace a slower ML library I was using (PyBrain). I have come across a confusing error that seems to be more of an issue between Anaconda and Theano but I was wondering if anyone here could provide any insight.

Here is a link to an issue on the Theano repository https://github.com/Theano/Theano/issues/1871 dealing with a similar issue. The fix suggested in that thread is to set the DYLD_FALLBACK_LIBRARY_PATH to .../anaconda/lib. After doing this, though, my issue persists.

I have the same exact issue and setting the environment variable didn't help either. Did you find a way to fix it?
