[petrux]

Steps to reproduce

1. just run pylint on the following python snippet:

   import tensorflow as tf
   next(tf.variable_scope('MyScope').gen)

Current behavior

For short, the error is E: 2, 5: Generator 'generator' has no 'gen' member (no-member).
Here follows the full pylint output.

petrux@machine:~$ cat scratch.py 
import tensorflow as tf
next(tf.variable_scope('MyScope').gen)

petrux@machine:~$ pylint scratch.py 
No config file found, using default configuration
************* Module liteflow.scratch
C:  1, 0: Missing module docstring (missing-docstring)
E:  2, 5: Generator 'generator' has no 'gen' member (no-member)

@petrux Hello, I'm having the same problem with the code as you in this project file: https://github.com/dkmfbk/dket May I ask you to tell me how you solved this problem?

[Pierre-Sassoulas]

There's a number of way to fix this see the documentation for no-member: https://pylint.pycqa.org/en/latest/user_guide/messages/error/no-member.html.

I'm going to close because this kind of thing should be handled in a pylint-tensorflow plugin or can be alleviated with configuration. And this is unlikely to be ever fixed in pylint.
