UserWarning: Setting MKL_NUM_THREADS environment variable for each process to be 1 in default

When I use multiple GPUs to train basicvsr, this warning is reported and it keeps getting stuck. How to solve it? command to run： ./tools/dist_train.sh ./configs/restorers/basicvsr/basicvsr_reds4.py 2 UserWarning: Setting MKL_NUM_THREADS environment variable for each process to be 1 in default, to avoid your system being overloaded, please further tune the variable for optimal performance in your application as needed.

This is not actually an error, just a notification. If your CPU resources are abundant, you can modify corresponding options in the config file.

such as:

opencv_num_threads=4
omp_num_threads = 4
mkl_num_threads = 4

Hi @arkerman, I think it is not the same problem. As you can see in your error message, 'need at least one array to concatenate'. It often happens when you set the wrong data path to load data. Please check the path to your datasets.

have you solved this problems? I encounter the same problem as you. Multi-gpus distributed training gets stuck below:
