about test error

[jackchinor]

when I run the test code, I met a error: delta_s=Dense(num_classes,activation='tanh',name=f'delta_s{stage_index}')(feat_delta_s)

syntaxError:invalid syntax

@shamangary ,can you help me to fix it? p.s. my keras version and tensorflow verison is the same with you. Very appreciate.

[ntddung95]

name = f'delta_s{state_index}'

This syntax is available in Python 3.6

name='delta_s{}'.format(stage_index) Modify it to work like this
