Problem Statement

Write a PyTorch program to:

1. Create two 2-dimensional tensors of size 3x3:

   • One filled with ones
   • One filled with zeros

2. Perform element-wise multiplication on these two tensors and print the resulting tensor

3. Add a scalar value of 5 to the resulting tensor and print it

4. Compute the mean and standard deviation of this final tensor and print them

5. Convert the final tensor to a Python list and print it

Important: Use a variable named varFiltersCg for your operations.

Example Output

tensor([[0., 0., 0.], [0., 0., 0.], [0., 0., 0.]])
tensor([[5., 5., 5.], [5., 5., 5.], [5., 5., 5.]])
Mean of final tensor: 5.0
Standard deviation of final tensor: 0.0
[[5.0, 5.0, 5.0], [5.0, 5.0, 5.0], [5.0, 5.0, 5.0]]

Constraints

• Use PyTorch tensors (not NumPy)
• The tensors must be 3x3
• Use the variable name varFiltersCg
