CLI fails with `torch.dtype` arguments

[ioangatop]

🐛 Bug report

The CLI seems to not be able to handle torch.dtype arguments; pretty important for torchvision ToDtype transform.

To reproduce

Using the CLI:

# main.py
import torch
from jsonargparse import CLI


def interface(dtype: torch.dtype) -> None:
    print(f"dtype: {dtype} ({type(dtype)})")

CLI(interface)

Run with:

python3 main.py torch.float32

Expected behaviour:

The above to print:

dtype: torch.float32 (<class 'torch.dtype'>)

Environment

• jsonargparse version (e.g., 4.8.0):
• Python version (e.g., 3.9):
• How jsonargparse was installed (e.g. pip install jsonargparse[all]):
• OS (e.g., Linux):
