Hi, @orrzohar,
I'm facing the same issue as described in input #24. I followed the installation instructions and used four TITAN (12G) GPUs to run the code. I set the batch size to 2 and reduced the learning rate from 2e-4 to 8e-5, as well as the lr_backbone from 2e-5 to 8e-6.
However, even after 2 epochs, the class_error metrics remain quite high, ranging from 80 to 100. Is this normal? If not, what could be causing this problem?

This value has been fluctuating, unstable
