Relu inplace ops making issues

[abhiagwl4262]

Thanks for your error report and we appreciate it a lot.

#Bug
RuntimeError: one of the variables needed for gradient computation has been modified by an inplace operation: [torch.cuda.FloatTensor [2, 128, 120, 160]], which is output 0 of ReluBackward0, is at version 3; expected version 0 instead. 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!

What command or script did I use

/tools/dist_train.sh configs/solov2/solov2_r50_fpn_8gpu_1x.py 1

I made data related changed to config
I am using custom data with 3 classes
