error when train and test : if 'caption' in anns[0]: IndexError: list index out of range

I'm training my own dataset with mask scoring rcnn. When I run with "configs/e2e_ms_rcnn_R_50_FPN_1x.yaml", error occurred.
error to do with training:
Traceback (most recent call last):

I have double checked my json file in "annotations", but really don't know what's wrong! Need your help! Thank you in advance!!

Hi, please, I also have a problem testing my model. Can you show me how you run tools/test_net.py. I used python tools/test_net.py --config-file "configs/e2e_ms_rcnn_R_50_FPN_1x.yaml" command but I get an error different from yours

  File "/home/eldad/anaconda3/lib/python3.7/site-packages/torch/nn/modules/module.py", line 489, in __call__
    result = self.forward(*input, **kwargs)

    x = torch.cat((x, mask_pool), 1)
RuntimeError: invalid argument 0: Sizes of tensors must match except in dimension 1. Got 5 and 20 in dimension 0 at /pytorch/aten/src/THC/generic/THCTensorMath.cu:83

Any idea?
