Unknown command line flag

Traceback (most recent call last):

absl.flags._exceptions.UnrecognizedFlagError: Unknown command line flag 'meta_dir'

how can i solve it?

[vigorem]

For this very specific error, I solved it by declaring the two missing flags (past it after line 28):

tf.app.flags.DEFINE_string("meta_dir", "", 'META_DIR')
tf.app.flags.DEFINE_string("save_dir", "", 'META_DIR')

This does the trick
