function:"validation_step" is not working when using --val_frac and --seed flag

[NiranjanChaudhari0929]

The function: " validation_step" present in clf.py at (

lmcontrol/src/lmcontrol/nn/clf.py

Line 171 in 1bde7b2

def validation_step(self, batch, batch_idx):

) does not run when --val_frac and --seed is used.

but,
The function "validation_step" works perfectly fine when we use --validation flag.

The flags are present at:
--val_frac:

lmcontrol/src/lmcontrol/nn/clf.py

Line 214 in 1bde7b2

grp.add_argument("--val_frac", type=float, default=None, help="Part of data to use for training (between 0 and 1)")

--seed:

lmcontrol/src/lmcontrol/nn/clf.py

Line 216 in 1bde7b2

parser.add_argument("--seed", type=int)
