TypeError: 'int' object is not callable

[IvanEvan]

Hi, Weidi .
Thank you for your prompt reply !!!
And sorry to interrupt again.
As you said yesterday, I can successfully load the pre-training model.
But I encountered a new mistake as the title shows.
This time I used the following command line:

python main.py --net resnet34s --batch_size 3 --gpu 0 --lr 0.001 --ghost_cluster 2 --vlad_cluster 8 --warmup_ratio 0.1 --optimizer adam --epochs 20 --multiprocess 1 --loss softmax --data_path ''

I know that the model loaded successfully through the information displayed in the terminal.
But after print Learning rate for epoch 1 is 0.0001., the new error occured.

**Exception in thread Thread-2:
Traceback (most recent call last):
File "/usr/local/anaconda3/envs/py3.6/lib/python3.6/threading.py", line 916, in _bootstrap_inner

sequence = list(range(len(self.sequence)))
TypeError: 'int' object is not c

I think it's a multi-process or multi-threading problem.
So I tried to set --multiprocess 0, or comment out areas of code that involve multiple processes.
But nothing changed.
I found one issues, he set --workers 0, so I changed fit_generator function's workers=0 in main.py.
A "new" error occured:

The same error TypeError: 'int' object is not callable occured, someone said that your custom variable name and the default function or class name duplicate will cause this problem.
I can't solve the problem, So I would like to ask if you have come across this problem, or have any ideas to solve it.

Sorry again for the interruption, and thanks in advance !!!
