Error when running train.sh

[Cathyttt]

when running train.sh, it came up with a error:

Traceback (most recent call last):‘
  File "./train_nmt.py", line 4, in <module>
    from nmt import train
  File "/home/tyt/style-trans/text_style_transfer-master/model/style_transfer/session_multi_decoder/nmt.py", line 4, in <module>

    raise Exception("The nvidia driver version installed with this OS "
Exception: The nvidia driver version installed with this OS does not give good results for reduction.Installing the nvidia driver available on the same download page as the cuda package will fix the problem: http://developer.nvidia.com/cuda-downloads

I think it's something wrong with theano or cuda, but I don't know how to fix it.

It seems the problem comes from theano. I recommend you to search "The nvidia driver version installed with this OS" in google. Some pages like "https://devtalk.nvidia.com/default/topic/1025598/mac-os-the-nvidia-driver-version-installed-with-this-os-does-not-give-good-results-for-reduction/" may help you solve the problem.

I fixed the bug above but here comes a new fault:

Traceback (most recent call last):
  File "./train_nmt.py", line 55, in <module>
    'reload': [False]})
  File "./train_nmt.py", line 42, in main

Can you provide the tendency of the ppl and the time the error happens (eg,, epoch)?

At the first of the training, here is the full log:

As the warning said, have you tried use the Theano flag'cxx=' (set to an empty string) to disable all ccode generation ? I think the error comes from the theano environment.

[Cathyttt]

I tried it and then it told me pygpu was disable.

problem solved. Data format.
