Issue parsing operators without arguments

[amjal]

I Followed the setup steps mentioned in the README.
When I run the replay job I get the following error:

Traceback (most recent call last):
File "/usr/lib/python3.10/runpy.py", line 196, in _run_module_as_main

File "/home/amir/chakra_replay/et_replay/et_replay_utils.py", line 154, in build_torchscript_func
r"^.*?(", "", input_types[0]
IndexError: list index out of range

Adding the following print to et_replay_utils.py:

print (n.op_schema)
    # items = [item for item in tmp[0].split(',') if item != ' *']
    types = [item for item in tmp[0].split(" ") if "," not in item][:-1]
    print(n.name, n.id, types)

I get the following output:

mkldnn::_is_mkldnn_acl_supported() -> bool _0
mkldnn::_is_mkldnn_acl_supported 75704 []

Looks like the code doesn't handle operators without input arguments.
