Describe the bug

Cannot import ttnn without torch

To Reproduce
Steps to reproduce the behavior:

>>> import ttnn
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/blozano/anaconda3/envs/py310/lib/python3.10/site-packages/ttnn/__init__.py", line 260, in <module>
    import ttnn.operations
  File "/home/blozano/anaconda3/envs/py310/lib/python3.10/site-packages/ttnn/operations/__init__.py", line 11, in <module>
    _module = loader.find_spec(module_name).loader.load_module(module_name)
  File "/home/blozano/anaconda3/envs/py310/lib/python3.10/site-packages/ttnn/operations/binary_backward.py", line 8, in <module>
    from ttnn.operations.complex_binary_backward import (
  File "/home/blozano/anaconda3/envs/py310/lib/python3.10/site-packages/ttnn/operations/complex_binary_backward.py", line 6, in <module>
    import torch
ModuleNotFoundError: No module named 'torch'

Expected behavior
I would expect that Tenstorrent's python module for accelerating neural networks on Tenstorrent would work without installing Meta's python module for accelerating neural networks.
