See original GitHub issueI get the following error when starting my training:
Traceback (most recent call last):
File "tr_baseline.py", line 75, in <module>
optimizer = Ranger21(params=model.parameters(), lr=learning_rate)
File "/mnt/Drive1/florian/msblob/Ranger21/ranger21/ranger21.py", line 179, in __init__
self.total_iterations = num_epochs * num_batches_per_epoch
TypeError: unsupported operand type(s) for *: 'NoneType' and 'NoneType'
initializing ranger with:
# ranger:
optimizer = Ranger21(params=model.parameters(), lr=learning_rate)
