use_cuda set to True in config file, but model runs on CPU

[LiuCMU]

Hi, I set "use_cuda": True in my configure file, but openchem only uses cpus when running on our cluster.

The following two screen shot are my configure file and output in the terminal.

I also tried to add --use_cuda=True as a flag to the bash command. From the terminal output, it seems that openchem knows to use cuda. But the machine has a problem in recognizing the use_cuda command.

Thanks!
