I I need to use Pytorch with open MPI, so I’m having to install it from source. I’m using CentOS 8.
while runnning - python setup.py install i’m running into the following error.
CMake Warning at caffe2/CMakeLists.txt:755 (add_library):
  Cannot generate a safe runtime search path for target torch_cpu because
  files in some directories may conflict with libraries in implicit
  directories:

    runtime library [libgomp.so.1] in /usr/lib/gcc/x86_64-redhat-linux/8 may be hidden by files in:
      /home/aditya/anaconda3/lib

  Some of these libraries may not be found correctly.
