Error in call to target 'torch.optim.adamw.AdamW'

[Khola-naseem]

Hello, I am facing this error even though in the config file I have defined the optim like this: optim: amp: enabled: true amp_dtype: bfloat16 optimizer: target: torch.optim.AdamW

Error Traceback (most recent call last): File "/usr/local/lib/python3.10/dist-packages/hydra/_internal/instantiate/_instantiate2.py", line 92, in _call_target return target(*args, **kwargs) TypeError: AdamW.init() missing 1 required positional argument: 'params'

The above exception was the direct cause of the following exception:
