.report() print issue with torch.SymInt / torch.SymFloat from torch.compile'd modules

[kylevedder]

Currently, readable_size() is defined to be

def readable_size(num_bytes: int) -> str:
    return '' if isnan(num_bytes) else '{:.2f}'.format(calmsize(num_bytes))

to inspect my error, I changed it to:

def readable_size(num_bytes: int) -> str:
    calm_res = calmsize(num_bytes)
    try:
        return '' if isnan(num_bytes) else '{:.2f}'.format(calm_res)
    except:
        breakpoint()

Where I have the following trace in PDB:

> /miniconda/lib/python3.11/site-packages/pytorch_memlab/utils.py(9)readable_size()->None
-> breakpoint()

*** TypeError: unsupported format string passed to SymFloat.__format__

This appears to be caused by a lack of support for torch.SymInt by calmsize, which are a product of torch.compile'd modules.

Can you post a minimal reproduce snippet to get SymInt
