使用ch_ppocr_server_v2.0这个模型，报错了

[CcgKaneki]

1、在百度网盘下载好了这个100多兆的rec.onnx文件
2、然后放在了onnxocr/models/ch_ppocr_server_v2.0/rec文件夹下，
3、在utils.py文件的def infer_args():中修改了配置为：
parser.add_argument("--det_model_dir", type=str, default='./onnxocr/models/ch_ppocr_server_v2.0/det/det.onnx')
parser.add_argument("--rec_model_dir", type=str, default='./onnxocr/models/ch_ppocr_server_v2.0/rec/rec.onnx')
parser.add_argument("--cls_model_dir", type=str, default='./onnxocr/models/ch_ppocr_server_v2.0/cls/cls.onnx')
这样修改以后，运行就报下边的错，把rec_model_dir这个参数改回原来的就不报错了，其他两项用ch_ppocr_server_v2.0的也没报错。

请问大神，这样配置是不是哪里有问题？需要怎么配置才能使用ch_ppocr_server_v2.0？另外问一下这两个模型有什么区别？谢谢啦！
