I got a RuntimeError, need help plz

[sfy-1739]

My setting is torch: 1.10 cuda: 11.3

error:

Hint: enable anomaly detection to find the operation that failed to compute its gradient, with torch.autograd.set_detect_anomaly(True).

When add “torch.autograd.set_detect_anomaly(True)”, the error:

Hint: the backtrace further above shows the operation that failed to compute its gradient. The variable in question was changed in there or anywhere later. Good luck!

How did you solve this problem?

Thank you！
