Compile Issue - No module named 'libKeOpstorchd5f55273e3'

[kheyer]

I'm trying to get KeOps working and I'm having compiler issues that appear to be related to compiling Pytorch bindings.

I read through similar issues (https://github.com/getkeops/keops/issues/28, https://github.com/getkeops/keops/issues/49, https://github.com/getkeops/keops/issues/8), but these mention fixes in v1.4 release. I'm running into the following issue using the v1.4 pip install.

Test script:

import pykeops
pykeops.verbose = True
pykeops.build_type = 'Debug'
pykeops.clean_pykeops()
pykeops.test_torch_bindings()

Terminal output:

Hi @kheyer ,

there is a mismatch between the detected CXX compiler

-- The CXX compiler identification is GNU 7.3.0
-- Check for working CXX compiler: /home/ubuntu/anaconda3/envs/pytorch_p36/bin/x86_64-conda_cos6-linux-gnu-c++
-- Check for working CXX compiler: /home/ubuntu/anaconda3/envs/pytorch_p36/bin/x86_64-conda_cos6-linux-gnu-c++ -- works

and the one you are expecting to use

$ g++ -v

Moreover, from my point of view, using the c++ compiler shipped by anaconda is not a good idea. You better have install a newer g++ from ubuntu apt repo. Here are your error:

Hi @bcharlier thanks for responding.

I tried setting Anaconda to use the Anaconda install of g++, which uses version 7.3.0

export CXX=/home/ubuntu/anaconda3/envs/pytorch_p36/bin/x86_64-conda_cos6-linux-gnu-g++

This successfully changes the compiler used:

... -- The CXX compiler identification is GNU 7.3.0
-- Check for working CXX compiler: /home/ubuntu/anaconda3/envs/pytorch_p36/bin/x86_64-conda_cos6-linux-gnu-g++
-- Check for working CXX compiler: /home/ubuntu/anaconda3/envs/pytorch_p36/bin/x86_64-conda_cos6-linux-gnu-g++ -- works

However the same errors are thrown.

I tried using the non-Anaconda version of g++

> which g++
/usr/bin/g++
> export CXX=/usr/bin/g++

Although this fails with

... CMake Error at /usr/local/lib/python3.5/dist-packages/cmake/data/share/cmake-3.13/Modules/CMakeTestCXXCompiler.cmake:45 (message):
  The C++ compiler

    "/usr/bin/g++"

  is not able to compile a simple test program.

I tried totally uninstalling the Anaconda compilers and doing a fresh install of g++ and cmake using apt-install, but the error persisted.

Searching around I found one reference to the following error:

/home/ubuntu/anaconda3/envs/pytorch_p36/x86_64-conda_cos6-linux-gnu/include/c++/7.3.0/bits/stl_pair.h(79): error: inline specifier allowed on function declarations only

On this issue, which points to CUDA compilation issues.

Do you have any thoughts on how to go about debugging this?

No change with your first attempt. This was the anaconda g++ already in use.

You definitely need a working decent c++ compiler on your system.

Do you have any thoughts on how to go about debugging this?

If you're admin on the machine

$sudo apt install g++-XX

where XX=6,7 or 8 should be the way to go. If you don't have the admin rights, send a mail to your IT and ask for the installation.

Installing g++8 fixes the "not able to compile" error but the compilation errors remain.

> sudo apt install g++-8
> which g++-8
/usr/bin/g++-8
> export CXX=/usr/bin/g++-8

At the start of compilation I see

... -- The CXX compiler identification is GNU 8.3.0
-- Check for working CXX compiler: /usr/bin/g++-8
-- Check for working CXX compiler: /usr/bin/g++-8 -- works

@fradav , an idea ?

[fradav]

Hello,

Please provide the whole cmake output, as it appears that a crucial flag have been borked in the process (-std=c++14). Did you clean your build dir when you upgraded to g++-8 (deleted the CmakeCache.txt file) ?

Regards,

[kheyer]

I ran lb clean and locate CMakeCache doesn't return anything. Here's the full output:

I noticed that some of the outputs related to nvcc have the "-std=c++17\" set, which might be the issue. According to the nvcc docs only c++ 03, 11 and 14 are supported flags. Do either of you know where this is being set? Thanks.

[kheyer]

I figured it out. $CXXFLAGS and $CXXFLAGS_USED on my machine specified -std=c++17. This may also be a conda thing but I'm not sure. Changing the flag to c++14 caused things to compile correctly.

And wow my GPU memory usage just dropped from 11 GB to 300 MB

Hi @kheyer , thanks for posting that solution - it works for me as well.

Would someone mind explaining how to set the CXXFLAGS environmental variable so that it persists? For instance I can set it once and run the test script, but then every time I re-open a shell or the conda env it returns to the -std=c++17.
Thanks
