My python scrip includes:
from keras.models import model_from_json model = model_from_json(open(\"test.json\").read()) model.load_weights(\"test.h5\") model.
This resolved the error:
pyinstaller -w --hidden-import=h5py.defs --hidden-import=h5py.utils --hidden-import=h5py.h5ac --hidden-import=h5py._proxy myscript.py
