TypeError: __init__() missing 1 required positional argument: 'classes_num'

可以问一下这个报错是为什么吗
Traceback (most recent call last):
File "train.py", line 236, in
main(cus_params, cus_logger)
File "train.py", line 27, in main
model = build_model(conf["model"])
File "/root/fish/projects/ocr_torch/nets/init.py", line 12, in build_model
module_class = eval(module_name)(**config)
TypeError: init() missing 1 required positional argument: 'classes_num'
