run bash install.sh error about flownet2-pytorch

[Qianli-ion]

Hi @Zhuysheng and @clarkren !
It seems like this issue can be addressed by creating a symbolic link from your cuda-8.0 directory to /usr/local/cuda. Try this (my cuda is installed at /usr/local/cuda-8.0 you can replace with yours),
sudo ln -s /usr/local/cuda-8.0 /usr/local/cuda
At least it addresses the installation problem for me.

@Zhuysheng , can you give more information about your environment where you run the install.sh?

[clarkren]

Hi , fitsumreda! I meet the same problem. My system is ubuntu14.04, with cuda8.0,cudnn6.0.

[fitsumreda]

@clarkren, @Zhuysheng,
Did you try to use the dockerfile in the repo?
That may help debug the cuda environment issue.

[clarkren]

@fitsumreda
I think I have correctly installed the cuda env. I tested the env like this:
"
Python 2.7.14 |Anaconda, Inc.| (default, Oct 27 2017, 18:21:12)
[GCC 7.2.0] on linux2
Type "help", "copyright", "credits" or "license" for more information.

import torch
x = torch.randn(2, 3)
x = x.cuda()
x
tensor([[ 1.7644, 0.6340, 0.9584],
[ 0.2991, 0.5439, -0.9146]], device='cuda:0')
"

Hi @Qianli-ion
I have tried that,but it seems not effective.

@Qianli-ion it solved my install problem,thanks

[Qianli-ion]

Hi @clarkren

It seems like the error you get right now is not the "cuda.h" problem. So I guess that symbolic link does solve your "cuda.h" problem?

Now regarding the new problem. From the error you get "‘for’ loop initial declarations are only allowed in C99 mode", it seems like to solve it you can try to add -std=c99 flag in your compilation script. I don't have this problem during my installation so I'm not 100% sure. Have you checked out this post, https://stackoverflow.com/questions/29338206/error-for-loop-initial-declarations-are-only-allowed-in-c99-mode?

[ShashiAdhikari]

@Qianli-ion it solved my install problem,thanks

Hi @Qianli-ion how did you solve the issue?
I try running the bash install.sh.
Error that is commands 'x86_64 -linux-gnc-gcc' failed with exit status 1
can you explain how to run it will be helpful.
Thank you
