NotImplementedError: Average pool operation with spatial rank == -2 is not implemented

[pzy2000]

BUG Log: Traceback (most recent call last): File "/opt/conda/envs/tf2onnx/lib/python3.7/site-packages/onnx2torch/node_converters/average_pool.py", line 29, in _ avgpool_class = _AVGPOOL_CLASS_FROM_SPATIAL_RANK[spatial_rank] KeyError: -2

The above exception was the direct cause of the following exception:

Traceback (most recent call last): File "issue_onnx2torch_001.py", line 4, in torch_model = convert(onnx_model_path) File "/opt/conda/envs/tf2onnx/lib/python3.7/site-packages/onnx2torch/converter.py", line 110, in convert torch_module, onnx_mapping = converter(onnx_node, onnx_graph) File "/opt/conda/envs/tf2onnx/lib/python3.7/site-packages/onnx2torch/node_converters/average_pool.py", line 33, in _ ) from exc NotImplementedError: Average pool operation with spatial rank == -2 is not implemented

Code to reproduce: from onnx2torch import convert

onnx_model_path = "vgg19-imagenet_origin-MDtype4-NLAll9-MDtype24-MDims26.onnx" torch_model = convert(onnx_model_path)
