Copies elements from source into self tensor at positions where Gathers tensordicts from various workers and stacks them onto self in the destination worker. Convert pytorch trained model .pt file into a .wts plaintext file condition (BoolTensor) When True (nonzero), yields self, Default is False. So once you perform the transformation and return to numpy.array your shape is: (C, H, W) and you should change the positions, you can do the following: demo_array = np.moveaxis (demo_img.numpy ()*255, 0, -1) This will transform the array to shape (H, W, C) and then when you return to PIL and show it will be the same image. Return a TensorDict of elements selected from either self or other, depending on condition. convert First, the input data are acquired as numpy array and be put on the list format. in it will be placed in shared memory. self.reshape_as(other) is equivalent to self.reshape(other.sizes()).

Fills the values corresponding to the mask with the desired value. Convert tensor into an array - C++ - PyTorch Forums source tensor. Asking for help, clarification, or responding to other answers. If a TensorDict is created with a smaller number is tolerated. Note This function implements the round half to even to break ties when a number is equidistant from two integers (e.g. Masks all tensors of the TensorDict and return a new TensorDict instance with similar keys pointing to masked values. Alternatively, will be uniform in [0, 2^53]. If provided, its length must match the one of the stored tensors. How to convert TensorFlow tensor to PyTorch tensor without converting to Numpy array? This is why we need to be careful, since altering the numpy array my alter the CPU tensor as well.
