ValueError: NodeDef mentions attr 'feature_win_len' not in Op

[qianyunw]

Hi,

thanks for sharing!

I am currently trying to run your code on my machine(Python 2.7& Tensorflow 1.12.0).
When I run command line "python run_voca.py", there are some problems, The following is the output, is there something wrong with my settings?

Thank you so much!!!

Hi,

can you please provide some more information about your setup? Did you download the trained DeepSpeech model (v0.1.0) from Mozilla/DeepSpeech (i.e. deepspeech-0.1.0-models.tar.gz)?

[qianyunw]

Hi,

thank you for your reply!
Yes, I downloaded deepspeech-0.5.0-models. Does the version affect the results? I will try 0.1.0 later!

[TimoBolkart]

Hi,

yes, the downloaded version matters as Mozilla changed some things in how to handle the input data. Please try with v0.1.0 and let me know if this fixes the problem.

Hi,

thank you so much(≧∇≦)ﾉ v0.1.0 fixes this problem perfectly!

[TimoBolkart]

Perfect, thanks for the feedback
