ImportError: cannot import name gpu_alloc_empty

i'm getting an import error on the gpu_alloc_empty in the following:

from theano.sandbox.cuda.basic_ops import (as_cuda_ndarray_variable,
                                           host_from_gpu,
                                           gpu_contiguous, HostFromGpu,
                                           gpu_alloc_empty)

the other modules by themselves work fine, just gpu_alloc_empty fails. i have cudnn installed and just reinstalled Theano with pip.

i figured it out. install the bleeding edge version of Theano instead of the latest on pip. can do via.

pip install --upgrade --no-deps git+git://github.com/Theano/Theano.git

FWIW: my version of Theano was initially too new (Theano/Theano@8d3a67b7) so I had to back-install the latest tagged release, which also worked for me.

pip uninstall theano
pip install --no-deps git+https://github.com/Theano/Theano.git@rel-0.7.1a1#egg=Theano==0.8.git
