How do you mix the two transforms from different package

[one-matrix]

for example：

preprocess=Compose([
    monai.transforms.EnsureChannelFirst(),
    torchvision.transforms.ToTensor(),
])

Hi @one-matrix, thank you for your interest here.

• You could use TorchVision, a wrapper transform for PyTorch TorchVision transform based on the specified transform name and args.
  

  MONAI/monai/transforms/utility/array.py

  Lines 1153 to 1159 in 354c9c2

  	class TorchVision:
  	"""
  	This is a wrapper transform for PyTorch TorchVision transform based on the specified transform name and args.
  	As most of the TorchVision transforms only work for PIL image and PyTorch Tensor, this transform expects input
  	data to be PyTorch Tensor, users can easily call `ToTensor` transform to convert a Numpy array to Tensor.
  	"""

• You could also write a custom transform to do such things, for more details refer to this discussion.
  Hope it can help you, thanks!
