training wrong （'bash' is not an internal or external command,）

[RookieCXL]

When I training the model，something wrong happen. Maybe because I use windows ，‘bash’ can't use？ Could you help me？

Hi,

it seems that the computation of TER and METEOR (which are wrappers around java) doesn't work in Windows. Those are not required for running the program. As a bypass, you can edit your file c:\users\think\src\keras-wrapper\keras_wrapper\extra\evaluation.py and comment the Line 51 and the Lines 55-56.

I hope this works.

Thanks，It works.
