Installation Problems on Centos 7.6

[lql341]

Has any one try install deepflame on Centos 7.6.

My configuration:

System: Centos 7.6
gcc compiler : GCC 7.3.1
MPI Compiler: OpenMPI 4.0.4

I followed the instructions 1-6 , and ran into glibc version errors at 6.

The problems are as follows:

I assume this require recompilation of libtorch.so instead of using precompiled ones.

Any comments or suggestions?

It seems like a C++ ABI problem, maybe your gcc compiler is too old. Try the following three methods to solve the problem.

• The precompiled Libtorch with Pre-cxx11 ABI is also produced, install this one and have a try!

• Update your gcc version (gcc 9.4.0 can install DeepFlame successfully)
• Try to compile Libtorch from source ~

I upgrade my gcc version to 11.2 and recompiled from scratch. I believe the problem comes from libtorch.

Can you provide a tutorial for compiling Libtorch?

The tutorial here ( https://github.com/pytorch/pytorch#from-source) can be helpful, gook luck !

Done! Rebuilding libtorch from source did solve the problem. Thank you!
