Hello! I run your code , but found errors below:

---

Traceback (most recent call last): File "F:/yyhaker/software/project/NamedEntityRecognition/src/ChineseNER/main.py", line 225, in if name == "main": File "D:\perhack\Anaconda3\envs\my_pytorch\lib\site-packages\tensorflow\python\platform\app.py", line 48, in run _sys.exit(main(_sys.argv[:1] + flags_passthrough)) File "F:/yyhaker/software/project/NamedEntityRecognition/src/ChineseNER/main.py", line 219, in main clean(FLAGS) File "F:/yyhaker/software/project/NamedEntityRecognition/src/ChineseNER/main.py", line 114, in train # create maps if not exist NameError: name 'os' is not defined

I have install the os module, and it can run correctly! What's wrong with it?

[yyHaker]

Oh, god! When I "import tensorflow as tf" before "import os", the code can run correctly! But when I "import tensorflow as tf" after "import os", it can't run correctly and give the above error, what's wrong with it?

这个问题你解决了吗？

[KaqiKaqi]

@qinya 我在这两行之间加了几行空行就行了

# encoding=utf8


import os

[weilonghu]

把# encoding=uft8去掉也可以，我不懂

@yyHaker : thanks for your suggestions. same thing happened to me, and changing the import flow fixed it. not sure why!
