getting "pygpu was configured but could not be imported" error while trying with OpenCL+Theano on AMD Radeon
I have followed the instructions from this:
https://gist.github.com/jarutis/ff28bca8cfb9ce0c8b1a
But then when I tried : THEANO_FLAGS=device=opencl0:0 python test.py
on the test file I am getting error:
ERROR (theano.sandbox.gpuarray): pygpu was configured but could not be imported Traceback (most recent call last): File "/home/mesayantan/.local/lib/python2.7/site-packages/theano/sandbox/gpuarray/init.py", line 20, in
import pygpu
File "/usr/src/gtest/clBLAS/build/libgpuarray/pygpu/init.py", line 7, in
from . import gpuarray, elemwise, reduction
File "/usr/src/gtest/clBLAS/build/libgpuarray/pygpu/elemwise.py", line 3, in
from .dtypes import dtype_to_ctype, get_common_dtype
File "/usr/src/gtest/clBLAS/build/libgpuarray/pygpu/dtypes.py", line 6, in
from . import gpuarray
ImportError: cannot import name gpuarray
I do not have good idea. I am using all these for the first time. I am working on Ubuntu 14.04 LTS. How can I resolve this error?
Answer
I fixed this issue with the step-by-step installation given in the lipgpuarray website!
Download
git clone https://github.com/Theano/libgpuarray.git
cd libgpuarray
Install libgpuarray
# extract or clone the source to <dir>
cd <dir>
mkdir Build
cd Build
# you can pass -DCMAKE_INSTALL_PREFIX=/path/to/somewhere to install to an alternate location
cmake .. -DCMAKE_BUILD_TYPE=Release # or Debug if you are investigating a crash
make
make install
cd ..
Install pygpu
# This must be done after libgpuarray is installed as per instructions above.
python setup.py build
python setup.py install

This worked for me! Good Luck
