标签: opencl theano amd

我已按照以下说明操作:

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

但是当我尝试时:THEANO_FLAGS = device = opencl0:0 python test.py
在测试文件上我收到错误:

错误(theano.sandbox.gpuarray):已配置pygpu但无法导入 Traceback(最近一次调用最后一次):   文件" /home/mesayantan/.local/lib/python2.7/site-packages/theano/sandbox/gpuarray/ init .py",第20行,

import pygpu

文件" / usr / src / gtest / clBLAS / build / libgpuarray / pygpu / init .py",第7行,

from . import gpuarray, elemwise, reduction

文件" /usr/src/gtest/clBLAS/build/libgpuarray/pygpu/elemwise.py" ;,第3行,

from .dtypes import dtype_to_ctype, get_common_dtype

文件" /usr/src/gtest/clBLAS/build/libgpuarray/pygpu/dtypes.py" ;,第6行,

from . import gpuarray

ImportError:无法导入名称gpuarray

我没有好主意。我是第一次使用这些。我正在研究Ubuntu 14.04 LTS。如何解决此错误?

我通过lipgpuarray网站提供的逐步安装解决了这个问题!

下载

git clone https://github.com/Theano/libgpuarray.git
cd libgpuarray

安装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 ..

安装pygpu

# This must be done after libgpuarray is installed as per instructions above.
python setup.py build
python setup.py install

这对我有用! 祝你好运

安装blas库似乎已经足够了。我正在为同样的问题做测试。

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

之后

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

关于python3

的构建和安装
python3 setup.py build
sudo -H python3 setup.py install

我希望它可以帮到你。现在我只缺少theano的开发版本。
