@Haonan-Qin Please try to use gcc>=5.0.

Haonan-Qin commented 5 years ago

@tianzhi0549 Thanks for your reply. In the first enviroment, when inputting 'python' we can obtain the output 'GCC 7.2.0 on linux', when inputting 'x86_64-conda_cos6-linux-gnu-gcc -version' we can obtain the output 'gcc version 7.2.0', when inputting 'gcc -v' we can obtain the output 'gcc version 5.4.0'. All of them >= 5.0 even though '5.4.0' of ubuntu is different from '7.2.0' of anaconda. So, is the bug made by the lower edition of gcc?

tianzhi0549 commented 5 years ago

@Haonan-Qin do you have x86_64-conda_cos6-linux-gnu-c++?

tianzhi0549 commented 5 years ago

@Haonan-Qin Please try to use gcc >= 5.0 but <= 6.0.

Haonan-Qin commented 5 years ago

@tianzhi0549 Thanks for your suggestion， I will try it immediately. But there is a basic question， does this project work with python2.7 or python3.6? When I try to run the code with python2.7, the error information has been changed, which seems to be more solvable. The error with python2.7 as follows.

running build running build_py running build_ext running develop error: can't create or remove files in install directory The following error occurred while trying to add or remove files in the installation directory: [Errno 13] Permission denied: '/opt/anaconda2/lib/python2.7/site-packages/test-easy-install-36314.write-test' The installation directory you specified (via --install-dir, --prefix, or the distutils default setting) was: /opt/anaconda2/lib/python2.7/site-packages/ Perhaps your account does not have write access to this directory? If the installation directory is a system-owned directory, you may need to sign in as the administrator or "root" account. If you do not have administrative access to this machine, you may wish to choose a different installation directory, preferably one that is listed in your PYTHONPATH environment variable.

tianzhi0549 commented 5 years ago

@Haonan-Qin It should work with both python versions. The error is because you do not have permission to write in the directory. Just try to add sudo before the command line.

It has no relationship with gcc version. Just pytorch version problem
