Theano CUDA delisting

Question

I'm relatively new to theano, and I want to run the mnist example on my GPU, but I get the following output:

Using gpu device 0: GeForce GTX 970M (CNMeM is disabled) Loading data... Building model and compiling functions... WARNING (theano.gof.compilelock): Overriding existing lock by dead process '9700' (I am process '10632') DEBUG: nvcc STDOUT mod.cu Creating library C:/Users/user/AppData/Local/Theano /compiledir_Windows-8-6.2.9200-Intel64_Family_6_Model_71_Stepping_1_GenuineIntel-3.4.3-64 /tmp55nlvvvo/m25b839e7715203be227800f03e7c8fe8.lib and object C:/Users/user/AppData/Local/Theano /compiledir_Windows-8-6.2.9200-Intel64_Family_6_Model_71_Stepping_1_GenuineIntel-3.4.3-64 /tmp55nlvvvo/m25b839e7715203be227800f03e7c8fe8.exp 

It continues to output DEBUG messages without mnist output. I have a working version of nvcc:

 C:\Users\user>nvcc --version nvcc: NVIDIA (R) Cuda compiler driver Copyright (c) 2005-2015 NVIDIA Corporation Built on Tue_Aug_11_14:49:10_CDT_2015 Cuda compilation tools, release 7.5, V7.5.17 

And my .theanorc file:

 [global] floatX = float32 device = gpu0 [nvcc] fastmath = True 

How can i solve this?

I have a similar problem. Search google and get the code. 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) 

Nvcc seems to have an error output.

But in my case, his conclusion looks like

DEBUG: nvcc STDOUT mod.cu

DEBUG: nvcc STDOUT mod.cu

Sometimes the program works fine after that, sometimes it doesn't work. It is very strange. Sorry, I can’t comment, so just send an answer.
