This is equivalent to calling torch.tensor_split (input, indices_or_sections, dim=0) (the split dimension is 0), except that if indices_or_sections is an integer it must evenly divide the split dimension or a runtime error will be thrown. This function is based on NumPy’s numpy.vsplit (). Parameters: can a hdmi cable change to a usb port
