Jul 04, 2021 · You can also use the Python interactive session as shown below: Using shape attribute: The tensor.shape is an alias to tensor.size(), though the shape is an attribute, and size() is a method. To verify this we can run the following in the interactive session. We can similarly cast this into a list using the list() method. Example:

You can directly convert python list to a pytorch Tensor by defining the dtype . For example, import torch a_list = [3,23,53,32,53] a_tensor ...

This video will show you how to convert a Python list object into a PyTorch tensor using the tensor operation. First, we import PyTorch. import torch Then we check the PyTorch version we are using. print (torch.__version__) We are using PyTorch version 0.4.1. Next, let’s create a Python list full of floating point numbers.

It accepts Tensor objects, numpy arrays, Python lists, and Python scalars. For example: import numpy as np def my_func(arg): ...

type(initial_python_list) We can see that the class is list, so bingo, it worked! What we want to do now is to convert this Python list to a TensorFlow tensor. To do this, we’ll use the tf.convert_to_tensor operation. tensor_from_list = tf.convert_to_tensor(initial_python_list) So tf.convert_to_tensor, and we pass in our Python list, and the ...
