ONNX file generation fails

[vp211991]

I am using the script tools/valid.py to export ONNX file. Here is the error stack.

Total Parameters: 29,561,182
----------------------------------------------------------------------------------------------------------------------------------
Total Multiply Adds (For Convolution and Linear Layers only): 45,385,056,256

Number of Layers
Conv2d : 395 layers   BatchNorm2d : 343 layers   ReLU : 306 layers   Bottleneck : 4 layers   BasicBlock : 105 layers   Upsample : 31 layers   HighResolutionModule : 8 layers   DeformConv2d : 34 layers   AdaptBlock : 34 layers

/home/vinay/.local/lib/python3.6/site-packages/torch/onnx/symbolic_helper.py:347: UserWarning: You are trying to export the model with onnx:Upsample for ONNX opset version 9. This operator might cause results to not match the expected results by PyTorch.
ONNX's Upsample/Resize operator did not match Pytorch's Interpolation until opset 11. Attributes to determine how to transform the input were added in onnx:Resize in opset 11 to support Pytorch's behavior (like coordinate_transformation_mode and nearest_mode).
We recommend using opset 11 and above for models using this operator.

I add the following line valid.py to export the model.

torch.onnx.export(model, dump_input, "/home/dekr.onnx", verbose=True)

The same file with the above line works fine in the other repository such as HRNet Image Classification and Human Pose Estimation.
