getting “pygpu was configured but could not be imported” error while trying with OpenCL+Theano on AMD Radeon

Question

I have followed the instructions from this:

https://gist.github.com/jarutis/ff28bca8cfb9ce0c8b1a

But then when I tried : THEANO_FLAGS=device=opencl0:0 python

Answer 1

Installing the blas library seems enough. I'm doing tests for the same problem.

cd ~
git clone https://github.com/clMathLibraries/clBLAS.git
cd clBLAS/
mkdir build
cd build/
sudo apt-cache search openblas
sudo apt-get install libopenblas-base libopenblas-dev
sudo apt-get install liblapack3gf liblapack-doc liblapack-dev
cmake ../src
make
sudo make install

And after that

git clone https://github.com/Theano/libgpuarray.git
cd libgpuarray
mkdir Build
cd Build
cmake .. -DCMAKE_BUILD_TYPE=Release

make
sudo make install
cd ..
sudo apt-get install cython
sudo apt-get install python-numpy python-scipy python-dev python-pip python-nose g++ libopenblas-dev git

Building and Installing with regard to python3

python3 setup.py build
sudo -H python3 setup.py install

I hope it can help you. Now just the dev version of theano is missing for me.
