OSError: [Errno 2] No such file or directory

Solution: write out JAVA_HOME manually, check java jre installation

2. errors in h5py

Relevant to keras-team/keras#3426

Solution: uninstall h5py, pip install h5py again.

Hello,

it seems that you have a problem with the evaluation, more precisely with the Meteor module. Please, make sure you have the coco-caption properly installed with the Meteor paraphrase data available in the right folder.

Cheers.
