Were you able to resolve it? I have the same issue

Ubuntu 18.04.6 LTS (bionic)
ml-agents: 0.27.0
ml-agents-envs: 0.27.0
Communicator API: 1.5.0
PyTorch: 1.8.1+cu102

 

Found the issue. Try running

setfacl -R -b <directoryname>

where "<directoryname>" is the directory with the build. It might have the special access privilege set.

 

I'm having the same issue and unfortunately your fix above doesn't work for me @dsb04163 did you manage to fix it another way? Thanks in advance!

 

i have the same problem, could you solve it?
