setup_cuda.py

[vicproon]

happened to me too.
another strange thing is that nvcc gives a warning about building something in arch sm_20, although i manually set it to compile only for sm_52

System Specs:

Windows 7 64 bit
Visual Studio 2015 x64
Python3.6
CUDA 8.0
Nvidia GTX 970

Full compile output

Here is an output of C:\Python36\python.exe setup_cuda.py build_ext > build.log 2>&1

[ShaneTsui]

Exactly the same problem😭

[shen-ee]

Does this have anything to do with CUDA version?I am using CUDA 8.0 and encountered the same problem.(Noticed that the source code is using CUDA 7.5)

[Lawliar]

same problem here, and I use CUDA8.0 too.

[Lawliar]

I removed 'ID=2' from the commandline, everything seems fine

[TinusChen]

The same problem here.

System
Windows 10 64 bit
Visual Studio 2015 x64
Python3.6
CUDA 8.0
Nvidia GTX 1050 Ti

my way to solve it:
1、add comment to see cmd details
for idx, c in enumerate(cmd):
print(cmd)

2、output:

3、copy the cmd above and remove ",ID=2" and then run it manually
work well

4、python setup_cuda.py install

Success!

for idx, c in enumerate(cmd):

@TinusChen where do you add these lines?

[yuezhilanyi]

my way to solve it: 1、add comment to see cmd details for idx, c in enumerate(cmd): print(cmd)

@TinusChen where do you add these lines?

maybe after line like this (i copy it from fgfa mxnet, much like faster rcnn)

cmd = ([c for c in cmd if c[0] != '/'] + [pass_on + ','.join(c for c in cmd if c[0] == '/')])

[Scott-Steinmetz]

For those coming upon this page with the same problem, add the following code to setup.py in the cudamat-master folder on line 94:
#Remove ',ID=2'
elif ',ID=2' in c: cmd[idx] = c[0:len(c)-5]
print(cmd)

Such that the elif is within the if statement inside of the for loop, and the print command is outside of the for loop mentioned by appyfizzA (not strictly necessary, but is convenient for double-checking if issues arise).

My issue was resolved after removing the ',ID=2' parameter, and cudamat successfully installed.
