Exploring the TensorFlow TypeError: ‘Tensor’ object does not support item assignment
This is an error which occurs when you try to assign to a tensor in tensorflow.
I will explain why this error takes place and how to fix it, while also trying to add other solutions that could solve the error.
# TypeError: 'Tensor' object does not support item assignment #
To solve the problem above, I have 2 solutions which worked for me, bellow is a detailed explanation of both.
Solution 1 : use tf.stack() and tf.unstack()
The problem occurs when you attempt to assign to a tensor, most developers do this without paying attention.
The solution is clear, stop assigning to a tensor, you can use tf.unstack to convert the tensor to a list. For example, if you have a tensor called ‘tensor1’, you can convert it to a list called ‘list1’ like this.
# list1 = tf.unstack(tensor1) #
You can then use tf.stack like this.
# list1[61:65] = [np.nan for x in range(5)] tensor1 = tf.stack(list1) #
using tf.stack() and tf.unstack() should be more than enough to solve your problem.
If this solution does not work, please try the solution bellow.
Solution 2 : use np.zeros() or torch.zeros() or use .Variable() with .zeros() followed by .assign()
Another option is to use numpy or Pytorch like this .zeros(mytensor-dims) . like in the examples bellow.
# val = np.zeros(mytensor-dims) val = torch.zeros(mytensor-dims) #
While mytensor-dims are the dimensions of the tensor at hand.
Another option is to use .zeros() inside .Variable() like this
# var=tensor2.Variable(tensor2.zeros(3, tensor2.int32)) #
Then assign .assign() like in the line bellow ( tenso2 is our tensor in this case )
# var=var[2].assign(1) #
The solutions above should be enough to solve the problem, if you like our effort make sure to consider donating to our Kofi account, there is a red button that you can use if you are feeling generous.
