Potential issue with GNU C++ Library

[o1iv3r]

Hi, I've been trying to run bitsandbytes for the first time using the diffusers package via --use_8bit_adam on a V100 with 16GB and get the following:

OSError: /lib64/libstdc++.so.6: version CXXABI_1.3.9' not found (required by /extradata/hf_env/lib/python3.9/site-packages/bitsandbytes/libbitsandbytes_cuda114_nocublaslt.so)`

Running CenOS 7 with the latest version of GNU C++, that is libstdc++-4.8.5-44.el7.x86_64.

I was wondering whether this is something that can be fixed or if bitsandbytes simply requires a newer CentOS version / another linux distribution like Ubuntu. Thanks!

Someone had a similar problem with a different program and needed to add to the linker path,

Thanks! I am not using conda. Upgrading gcc worked like this:

sudo yum install centos-release-scl
sudo yum install devtoolset-11-gcc*
scl enable devtoolset-11 bash
source /opt/rh/devtoolset-11/enable # run before script or add to ~/.bash_profile

Did not solve my issue though, but I think this is not library related so I'll close this issue.

Now I understand the solution on stackoverflow. One simply "borrows" the library from anaconda because it is there. So my solution was to add a path to a directory with a newer version of libstdc++.so.6:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/anaconda/envs/py38/lib/ # add path to the end, keeping all the others

I found the path '/anaconda/envs/py38/lib' via

sudo find / -name "libstdc++.so.6*" # get path of file (directory, not including file name)

To verify that the file support the right version one can use

strings /anaconda/envs/py38/lib/libstdc++.so.6 | grep CXXABI
