[theano-users] NameError: global name 'CVM' is not defined

Note, the Compute Canada cluster problem is independent of Theano, we also
have it ourself. Do not install anaconda manually yourself. Otherwise, you
will need to "fix" the installation due to the strange Compute Canada
configuration that end up with the error you show.

It should work with there software stack (but this will request you to
manually build libgpuarray/pygpu).

They also have beta doc on how to install conda yourself in a way that it
will work with Theano:
https://docs.computecanada.ca/wiki/Anaconda

I also suggest that you update Theano to the dev version or the last beta.
It have many great new features.

Also, check this page to use the new GPU interface:

After looking at previous posts, the fix seems to be to remove ~/.theano
directory. However, this does not work for me. The code runs file on my
school servers, but fails on compute canada clusters.
Any thoughts ? I'm running theano=0.9 and lasagne='0.2.dev1'
Thanks,
Lucas
