ImportError: No module named conv_bc01

[ghost]

Ubuntu 14.04 LTS. CUDA 7.5. However, I installed cudarray without cuda support. And after installation I got:

grinya@mypc:~/cudarray$ python import cudarray CUDArray: CUDA back-end not available, using NumPy. Traceback (most recent call last): File "", line 1, in File "cudarray/init.py", line 40, in from .numpy_backend import File "cudarray/numpy_backend/init.py", line 2, in from .nnet import File "cudarray/numpy_backend/nnet/init.py", line 3, in from .conv_bc01 import * ImportError: No module named conv_bc01

But the file in the directory "cudarray/numpy_backend/nnet" does exist. I do not understand this error.

Could the installation have failed? I assume you have run python setup.py --without-cuda install. Make sure a recent version of Cython is installed.

I do not think so, because during installation there were no errors. Yes, I used sudo python setup.py --without-cuda install. I have latest Cython. Version 0.23.4

Ok, I'll try it out then! :)

Here is a log of installation

Also, my parameters in makefile:

CUDA_PREFIX = /usr/local/cuda INSTALL_PREFIX = /home/grinya/anaconda2 CUDNN_ENABLED = 0

Thanks for the info, I can't reproduce the error. Try uninstalling CUDArray with pip uninstall cudarray (try multiple times to make sure all installations are removed). Then clean temporary CUDArray files with python setup.py clean. Finally, try installing again. If this doesn't work, you might want to try another Python distribution. I recommend Anaconda Python.

Well, I'm using Anaconda Python 2.7. pip uninstall cudarray tells that Cannot uninstall requirement cudarray, not installed Just tried re-installation after python setup.py clean. The same problem.

[andersbll]

I see! Can you try installing without sudo?

[ghost]

Oh, smth different. At least I can see my Anaconda path in the log:

grinya@grinyamipt:~/cudarray$ python setup.py --without-cuda install /home/grinya/anaconda2/lib/python2.7/site-packages/setuptools-19.2-py2.7.egg/setuptools/dist.py:284: UserWarning: Normalizing '0.1.dev' to '0.1.dev0' running install running bdist_egg running egg_info writing requirements to cudarray.egg-info/requires.txt error: [Errno 13] Permission denied: 'cudarray.egg-info/requires.txt'

[andersbll]

This is probably because the previous installation was with sudo. Make sure to uninstall CUDArray first (uninstall with sudo, that is).

[ghost]

Tried as you said. The same problem ImportError: No module named conv_bc01 after installation without sudo. Here is a log

I do not understand, but running python from a different directory (instead of cudarray's directory) works fine. And there is no ImportError =)

[andersbll]

Great! The reason why it didn't work was because Python tried to import cudarray from your working directory. This failed as the cythonized files are stored in a separate build directory. Another time If you want to store cythonized files along with your python code you should install with python setup.py develop.

Thank you!
