GpuArrayException: No cuda device available尝试解决

问题:

在import keras或import ttheano时出现了以下:

 

>>> import keras
Using Theano backend.
ERROR (theano.gpuarray): Could not initialize pygpu, support disabled
Traceback (most recent call last):
  File "/data_d/old_home/home/.conda/envs/lib/python2.7/site-packages/theano/gpuarray/__init__.py", line 227, in

  File "pygpu/gpuarray.pyx", line 587, in pygpu.gpuarray.pygpu_init
GpuArrayException: No cuda device available

尝试了pip uninstall theano并且使用conda install theano安装后,出现了更为奇怪的问题,搜索之后发现是由于theano1.0.4和numpy16.0出现不兼容等问题,所以进行了卸载。

重新使用pip install theano之后,进行操作,仍旧是同样的错误:

>>> import theano
ERROR (theano.gpuarray): Could not initialize pygpu, support disabled
Traceback (most recent call last):
  File "/data_d/old_home/home/.conda/envs/ib/python2.7/site-packages/theano/gpuarray/__init__.py", line 227, in

  File "pygpu/gpuarray.pyx", line 587, in pygpu.gpuarray.pygpu_init
GpuArrayException: No cuda device available

其他配置如下:

[global]
floatX = float32
device =cuda
[cuda]
root=/usr/local/cuda-8.0

##.theanorc文件
echo $PATH
/data_d/old_home/home/.conda/envs/bin:/usr/local/cuda-8.0/bin:/data_d/public/miniconda2/bin:/usr/local/cuda-9.0/bin:/usr/local/sbin:

CUDA_HOME=/usr/local/cuda-8.0
PATH="$PATH:/usr/local/cuda-8.0/bin"
LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/usr/local/cuda-8.0/lib64:/usr/local/cuda-8.0/extras/CUPTI/lib64"

#.bashrc文件
at /usr/local/cuda/include/cudnn.h | grep CUDNN_MAJOR -A 2
#define CUDNN_MAJOR      6
#define CUDNN_MINOR      0
#define CUDNN_PATCHLEVEL 21

所使用的theano版本为1.0.4,对应的pygpu为0.7.6。

是否是cuda-8.0文件夹的所有者被改变?不行。

跑测试程序也是同样的报错:

 尝试一:

修改配置文件,改为了cuda0,结果import theano时:

[global]
floatX = float32
device =cuda0
[cuda]
root=/usr/local/cuda-8.0
>>> import theano

GpuArrayException: GPU is too old for CUDA version

在https://blog.csdn.net/qq_33200967/article/details/80689543看到,需要检查cuda是否安装成功,由于直接用make报错,https://devtalk.nvidia.com/default/topic/1048902/cuda-setup-and-installation/cuda-samples-ubuntu-make-file-errors/,

所以使用了sudo make -k,发现输出结果为:

cudnn                     7.3.1                cuda10.0_0  

似乎版本过高,https://blog.csdn.net/li57681522/article/details/82491617

安装的cudatoolkit和cudnn程序包版本是:10.0

but实际上,我根本就没有安装过cuda10.0。

所以尝试卸载

cudnn                     6.0.21                cuda8.0_0

 

查询结果如上。

结果依旧同样的错误。

GpuArrayException: No cuda device available

 

 

尝试在新环境下重新安装Cuda等。https://blog.csdn.net/lyy14011305/article/details/59500819

按照这个http://deeplearning.net/software/theano/install_ubuntu.html安装numpy\theano等包时,出现以下问题:

Traceback (most recent call last):
  File "", line 1, in 
  File "/data_d/old_home/home/.conda/envs/xhs2/lib/python2.7/site-packages/theano/__init__.py", line 156, in 
    import theano.gpuarray

。。。
AttributeError: ('The following error happened while compiling the node', DnnVersion(), '\n', "'module' object has no attribute '_get_ndarray_c_version'")

 

https://github.com/pymc-devs/pymc3/issues/3340的解决办法是将theano升级为1.0.4(conda安装的为1.0.3),但是在升级时遇到了问题:

 conda install theano=1.0.4
Fetching package metadata ...........

没有了上面的AttributeError的错误,但是之后报的错仍旧是一模一样,当.theanorc中device =cuda0时,报错:

GpuArrayException: GPU is too old for CUDA version

 

当设置为:device =cuda时,报错:

GpuArrayException: No cuda device available

 

//绝望。
