Unable to print out Ranger21 Optimizer

[Interpause]

Unable to print out the optimizer:

optimizer = Ranger21(model.parameters(), 1000)
print(optimizer)

    print(optimizer)
TypeError: 'str' object is not callable

I believe it is due to the @property decorator at

pytorch_optimizer/pytorch_optimizer/optimizer/ranger21.py

Line 132 in edee372

def __str__(self) -> str:

. The __str__ dunder is supposed to be a function rather than a property.

Hello, Thanks for the report!

you're right __str__ method is supposed to be a function, it's my mistake. I'll fix it right away.

[kozistr]

now you can use v2.5.1 with the fix.

Thank you!

No problem, thanks for maintaining the optimizers.
