warning for not being able to determine streams size #25

Closed DmitryKey closed 9 years ago

DmitryKey commented 9 years ago

Hi!

Upon starting training from a saved state, I see this warning in the logs. Should I be worried about it and can it be fixed?

You can ignore them. It is complicated detail.

The UserWarning is now removed if you update Theano to the latest development version.

The RuntimeWarning is related by numpy, but you can ignore it.
