================================windows length is -1 Traceback (most recent call last): File "./datasets/preprocess.py", line 72, in write_statistics(character, './datasets/Mixamo/mean_var/') File "./datasets/preprocess.py", line 34, in write_statistics dataset = MotionData(new_args) File "/home/wuxiaoliang/docker/motion_retarget/deep-motion-editing/retargeting/datasets/motion_dataset.py", line 33, in init new_windows = self.get_windows(motions) File "/home/wuxiaoliang/docker/motion_retarget/deep-motion-editing/retargeting/datasets/motion_dataset.py", line 106, in get_windows return torch.cat(new_windows) RuntimeError: There were no tensor arguments to this function (e.g., you passed an empty list of Tensors), but no fallback function is registered for schema aten::_cat. This usually means that this function requires a non-empty list of Tensors. Available functions are [CPUTensorId, CUDATensorId, QuantizedCPUTensorId, VariableTensorId]

how to solve the problem? @kfiraberman

BVH files in wild can be very different, thus we can only promise our code working on provided dataset without any change. Some minor changes could be inevitable in order to work on your own dataset. Besides, we welcome all pull requests that enhance compatibility and robustness.
