SyntaxError: invalid syntax

[RuoyuChen10]

Thanks for your contribution. When I try to train a face model:

from tensorflow import keras
import losses, train, models
import tensorflow_addons as tfa

# Celeb-A
data_path = '/home/cry/J-20/Datasets/CelebA/Img_cls/img_align_celeba'
model_path = "ckpt/TT_r100_max_pool_E_prelu_dr04_lr_01_l2_5e4_adaface_emb512_sgd_m09_bs512_glint360k_64_only_margin_SG_scale_true_bias_false_random_100_partial4_basic_model_latest.h5"
save_path = "keras-ArcFace-R100-Celeb-A.h5"


eval_paths = ['/datasets/faces_emore/lfw.bin', 
              '/datasets/faces_emore/cfp_fp.bin', 
              '/datasets/faces_emore/agedb_30.bin']

tt = train.Train(data_path, save_path=save_path, eval_paths=eval_paths,
                model=model_path, batch_size=512, random_status=0,
                lr_base=0.1, lr_decay=0.5, lr_decay_steps=16, lr_min=1e-5)

optimizer = tfa.optimizers.SGDW(learning_rate=0.1, momentum=0.9, weight_decay=5e-5)
sch = [
#   {"loss": losses.ArcfaceLoss(scale=16), "epoch": 5, "optimizer": optimizer},
#   {"loss": losses.ArcfaceLoss(scale=32), "epoch": 5},
  {"loss": losses.ArcfaceLoss(scale=64), "epoch": 35},
  # {"loss": losses.ArcfaceLoss(), "epoch": 20, "triplet": 64, "alpha": 0.35},
]
tt.train(sch, 0)

It occurred a bug in train.py:

Traceback (most recent call last):
  File "fine-tuning-CelebA.py", line 2, in <module>
    import losses, train, models
  File "/home/cry/H6-K/Keras_insightface/train.py", line 381
    if not hasattr(cur_optimizer, "_variables") and hasattr(cur_optimizer, "_optimizer"), hasattr(cur_optimizer._optimizer, "_variables"):
                                                                                        ^
SyntaxError: invalid syntax

How to modify? Can I write as:

if not hasattr(cur_optimizer, "_variables") and hasattr(cur_optimizer, "_optimizer") and hasattr(cur_optimizer._optimizer, "_variables"):

Yes, you are right, and it's my fault.
