PyTorch Compatibility Issue with MATLAB Engine

I'm trying to use MATLAB Engine to extract features for a PyTorch model, but I'm receiving the following error.

File "xxxx", line 22, in <module>

import torch

File "/home/lab/anaconda3/lib/python3.6/site-packages/torch/__init__.py", line 81, in <module>

from torch._C import *

ImportError: /usr/local/MATLAB/R2019b/extern/engines/python/dist/matlab/engine/glnxa64/../../../../../../../sys/os/glnxa64/libstdc++.so.6: version `CXXABI_1.3.11' not found (required by /home/lab/anaconda3/lib/python3.6/site-packages/torch/lib/libtorch_python.so)

Interestingly, the error occurs on the line where I try to import PyTorch, not where I import MATLAB Engine. I was previously able to import PyTorch prior to installing MATLAB Runtime. I'm running Ubuntu 16.04.

Any ideas on what I'm doing wrong?

It turns out that this was not a MATLAB-specific issue, but rather an issue with PyTorch. I upgraded the CUDA version but did not re-install PyTorch. I solved this problem by upgrading to a newer version of PyTorch.

Upgrading torch did not work for me.

I solved the issue by switching the order of imports, i.e., importing torch first gives me errors but importing matlab.engine prior to importing torch worked without errors.

Kevin, do you want to help us with this? Switch the order of imports, and see if you can import the two in both order, with the latest torch release. Thanks in advance.
