Consider using one of the following signatures instead:

/home/earhian/anaconda3/envs/maskrcnn/lib/python3.7/site-packages/torch/optim/lr_scheduler.py:123: UserWarning: Detected call of `lr_scheduler.step()` before `optimizer.step()`. In PyTorch 1.1.0 and later, you should call them in the opposite order: `optimizer.step()` before `lr_scheduler.step()`. Failure to do this will result in PyTorch skipping the first value of the learning rate schedule. See more details at https://pytorch.org/docs/stable/optim.html#how-to-adjust-learning-rate

The reason is that the data set I trained is 70. Coco has a total of 80 categories. It is
clearly written in coco.py. I haven’t read it before haha. When the training base category is 70, the first 70 categories correspond to 1 ~ 79. Change num_classes to 81 to run successfully
# first 40 categories: 1 ~ 44; first 70 categories: 1 ~ 79; first 75 categories: 1 ~ 85
# second 40 categories: 45 ~ 91; second 10 categories: 80 ~ 91; second 5 categories: 86 ~ 91
# totally 80 categories
