Hi,
it seems an error while obtaining the TER metric. I think it can be due to the use of Windows. I never tested the software (and I don't intend to) for Windows.
However, the computation of TER is not required. So, as a bypass, you can edit the file c:\users\f.fernandes\appdata\local\programs\python\python36\scripts\src\keras-wrapper\keras_wrapper\extra\evaluation.py
and comment the Line 51.
Cheers
Thank you Alvaro. Now faced with another issue. I am using my Windows laptop which is a cpu based. Do you suggest using Linux VM with GPU?

Hi,
this is a similar issue. You should comment Lines 55-56 from the same file.
I strongly recommend you to use a GPU. Otherwise, the training would be prohibitively slow.
Thank you so much. We have a GPU VM that we had stopped because even after 194k steps 2 weeks of GPU instance the translation quality from French to English did not improve link. Only if I am 60% sure would restart the GPU instance. As the translation quality depends on the dataset. Would you be aware of any location from where we could download and use the French to English or Hindi to English dataset that has a high translation quality. Also could we resume the training with the changed dataset?
The overall performance of a NMT (or SMT) system heavily depends on the quantity and quality of the data. You can check the WMT'18 for obtaining large datasets.
Moreover, the choice of hyperparameters, regularization strategies, etc of NMT is a critical process. I recommend you to read some tutorials on NMT (https://arxiv.org/pdf/1703.01619.pdf or https://arxiv.org/pdf/1709.07809.pdf).
Error while training with the following command python main.py.
Finally training hangs with the following error. How do we resolve the error?
