RuntimeError: do not find download file frozen_model.pb

[komorebi566]

Hello，I had some problems during freezing the frozen_model.pb
An error is HYDU_create_process (utils/launch/launch.c:74): execvp error on file export (No such file or directory),
I guess something went wrong with the order:
mpirun -machinefile $PBS_NODEFILE -n 1 export CUDA_VISIBLE_DEVICES=0 && dp freeze 1>> train.log 2>> train.log
My dpgen version is 0.10.6
numpy 1.22.3
dpdata 0.2.7
pymatgen unknown version or path
monty 2022.4.26
ase 3.22.1
paramiko 2.8.1
custodian 2022.5.26
Thanks for any help~

I don't know how you generated such command, but the correct way to run multiple commands with mpi is

mpirun -machinefile $PBS_NODEFILE -n 1 sh -c "export CUDA_VISIBLE_DEVICES=0 && dp freeze" 1>> train.log 2>> train.log

I found this command in the .sub file generated by dpgen.
But I'm sorry that I cannot show some details for you, because I changed the command "with_mpi": false in machine.json, and it was successfully frozen.
