Is cltorch building and testing applicable for RHEL 7.2?

[streamhsa]

Hi, I need some info about support of this app on RHEL 7.2. Is it supported? After doing git clone to local setup, I am checking "install.sh". Inside that file, for RHEL OS, compiler and all are not defined so i am getting error "cmake compiler is not found". Can i get RHEL supported "install.sh" if RHEL is supported and If any handy page which i can follow to build on RHEL 7.2 is nice.

Thanks

Its supported in the sense that it should probably be possible to make it work, and I'm happy to answer questions about it, but not in the sense that I test on it, or have an RHEL installation available, or personally modify the script to work with RHEL.

I would think the first steps would be:

• figure out how to install cmake on RHEL 7.2
• install cmake
• figure out how to modify the script to install cmake (this is optional really; you could simply install cmake by hand, then rerun the script)

(actually, one option could be to use https://github.com/torch/distro to install a non-opencl torch, get that working; then retry the opencl version, using what you've learned from the non-opencl version as a guide)

Hi, Somehow i proceed one step further. I tried "bash install-deps" command on RHEL7.2. It's saying "=>only Ubuntu, ele.OS, Fedora and CentOS distribution supported" Now, i ignored it and ran "./install.sh". I am getting below error and compilation terminated. I don't know it's due to install-deps command did not work or something else. Full log is attached.

Hi. Ok cool! This particular library, I think you can fix with a command something like:

yum install readline-devel

[streamhsa]

Thanks a lot. It resolves building issues and i went one step ahead. :) I built successfully but still tests are failing with some error. Below 2 tests are failing, PFA. torch.zip luajit -l torch -e 'torch.test()' luajit -l nn -e 'nn.test()'

Below 2 are passing: luajit -l cltorch -e 'cltorch.test()' luajit -l clnn -e 'clnn.test()'

Can you give me the full output? (eg via https://gist.github.com )

(oh, just noticed the zip file. Opening :-) )

Ah, looks like you're missing a BLAS. Can you somehow install:

• a blas, and
• an lapack

... and then reinstall//rebuild torch/nn, and try again please?

[streamhsa]

I have checked already, blas ,openblas and lapack are installed. Still it's failing. But i am seeing openblas related file not found too while building. Also, some failure observed while building related to QT4 not found but QT4 is also installed on the system.

Ok. torch looks for them using the FindBLAS.cmake and FindLAPACK.cmake files, in https://github.com/torch/torch7/tree/master/lib/TH/cmake

It looks like you might be able to prod them into finding your libraries by adding the .sos to CMAKE_LIBRARY_PATH, https://github.com/torch/distro/blob/master/install.sh#L41

Otherwise, you might want to hack the paths in the Findxxx.cmake files a bit, eg https://github.com/torch/torch7/blob/master/lib/TH/cmake/FindBLAS.cmake#L70

(to be honest, if the cltorch and clnn tests are all passing, you could just jump straight to trying whatever it is you want to try, and ignore the non-gpu blas errors. I assume from your name, and your github followers/followees that you are AMD? So, I guess you mostly want to jump straight into looking at convolution perhaps? This should work just fine without non-gpu blas installed)

[hughperkins]

(by the way, qt is not required, unless you want to start using jupyter-type notebooks, and other gui things)

Thanks a lot for the quick help. We can close this thread.

[hughperkins]

Cool :-) Let me know if you have any questions.
