[英]Theano CUDA exception
I'm relatively new to theano and I want to run the mnist example on my GPU but I get the following output: 我是theano的新手,我想在我的GPU上运行mnist示例,但得到以下输出:
Using gpu device 0: GeForce GTX 970M (CNMeM is disabled)
Loading data...

It keeps outputting DEBUG messages without any output of mnist. 它保持输出DEBUG消息而没有mnist的任何输出。 I have a working version of nvcc:
我有nvcc的工作版本:
C:\Users\user>nvcc --version

And my .theanorc
file: 和我的
.theanorc
文件:
[global]
floatX = float32
device = gpu0
[nvcc]
fastmath = True
How can I solve this? 我该如何解决?
I have a similar problem. 我有一个类似的问题。 Search google and get the code.
搜索谷歌并获取代码。 https://github.com/Theano/Theano/blob/master/theano/sandbox/cuda/nvcc_compiler.py

p = subprocess.Popen(
cmd, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
nvcc_stdout_raw, nvcc_stderr_raw = p.communicate()[:2]
console_encoding = getpreferredencoding()
nvcc_stdout = decode_with(nvcc_stdout_raw, console_encoding)
nvcc_stderr = decode_with(nvcc_stderr_raw, console_encoding)
if nvcc_stdout:
# this doesn't happen to my knowledge
print("DEBUG: nvcc STDOUT", nvcc_stdout, file=sys.stderr)
It seems to nvcc have error output. 看来nvcc有错误输出。
But in my occasion, its output looks like 但是在我的情况下,它的输出看起来像
DEBUG: nvcc STDOUT mod.cu
调试:nvcc STDOUT mod.cu
DEBUG: nvcc STDOUT mod.cu
调试:nvcc STDOUT mod.cu
Sometimes the program work fine after this, sometimes doesn't work. 在此之后,有时程序可以正常运行,有时不起作用。 It's very strange.
真奇怪 Sorry I can not make comment, so I just post the answer.
抱歉,我无法发表评论,所以我只发布了答案。
