how to resolve this problems? thanks

[DerekChia]

I got it to work by first converting the GRID video to frames using scripts/extract_mouth_batch.py and made the changes proposed by @acarlos in #37 . Feel free to email me (email in profile) if you have difficulty running or getting started.

[gzz666]

@DerekChia Sorry,I just saw your reply.Thank you very much

[gzz666]

@DerekChia Hey，I got following error ： File "D:\Anaconda3\lib\site-packages\skvideo\io\io.py", line 240, in vreader assert _HAS_FFMPEG, "Cannot find installation of ffmpeg." AssertionError: Cannot find installation of ffmpeg.

I have installed ffmpeg too, and I still can`t fix it. How did you resolve the problem?

[DerekChia]

@gzz666 I'm running Ubuntu, not Windows, so I cannot help you with the FFMPEG installation. Sorry.

[gzz666]

I solved this question.I'm runing also Ubuntu16.04. but I have another issue.Error loading videos...in the training.py do you know how to solve?

[DerekChia]

@gzz666 Can you paste the entire error message here?

This is he entire error message .thanks

[gzz666]

@DerekChia I have resolved this problem.

[gzz666]

@DerekChia can you tell me how to solved this tissue？from lipnet.lipreading.generators import RandomSplitGenerator ImportError: No module named lipnet.lipreading.generators

[shoaibkh]

@DerekChia I have resolved this problem.

Sir can you tell me that how you can resolve it i shall be very thank full to you

[jiagnhaiyang]

如何解决这个问题？谢谢

@DerekChia我已经解决了这个问题。

大神您好，您这个问题是怎么解决的？

[jeonsanghun]

I solved it, and I am converting from python 2.7 to 3.6 code
