split DSSM model got error

[ucas010]

hi,dear 大佬
from the issue I tried the split script
but got the bug bellow:

python  ../easy_rec/python/tools/split_model_pai.py --model_dir ../conf/dssm/_ckpt/export/final/  --user_model_dir ../conf/dssm/userModel/ --item_model_dir ../conf/dssm/itemModel/
Traceback (most recent call last):

/conf/dssm/_ckpt/export/final/ 目录下确认模型导出正确么？

[ucas010]

python -m easy_rec.python.train_eval这个就是包括导出模型了吧，不用再python -m easy_rec.python.export了吧。
检查如下，
drwxr-xr-x 4 root root 59 3月 27 18:54 1679914493
这个文件夹下面

-rw-r--r-- 1 root root 204K 3月  27 18:54 saved_model.pb
drwxr-xr-x 2 root root   66 3月  27 18:54 variables
drwxr-xr-x 2 root root   29 3月  27 18:54 assets

ml-1m数据集AUC=0.72这个正常么？

ml-1m数据集AUC=0.72这个正常么？

是正常的，可以尝试通过调参提升指标或者使用真实业务数据。

python -m easy_rec.python.train_eval

python -m easy_rec.python.train_eval 这个是训练和评估，没有导出模型呀
