problem running test_run.sh

[jbujons]

Hello,
I have just download and tried DLScore. When trying to run the test file to check that everything is ok, I got the following error:

---

bash test_run.sh
Using TensorFlow backend.
setting PYTHONHOME environment

Command-line parameters used:
Receptor: samples/10gs/10gs_protein.pdbqt

AttributeError: 'str' object has no attribute 'decode'

Lines 874-881 of file "saving.py" show:

---

:
if 'keras_version' in f.attrs:
original_keras_version = f.attrs['keras_version'].decode('utf8')
else:
original_keras_version = '1'
if 'backend' in f.attrs:
original_backend = f.attrs['backend'].decode('utf8')
else:
original_backend = None
:

but if I change both if statements to

---

:
if 'keras_version' in f.attrs:
original_keras_version = '1'
else:
original_keras_version = '1'
if 'backend' in f.attrs:
original_backend = None
else:
original_backend = None
:

then the calculation gets to the end giving the output:

DLSCORE OUTPUT: [{'vina_output': -6.7202, 'nnscore': 4.810024302277946, 'dlscore': 5.851217412948609}]

which I guess is OK.

My question: the changes made to the file saving.py might alter or affect the results of DLScore in any way or can I safely use the software in this way? I understand that the modified lines are only querying the keras and backend versions, so it might be that this is not so important for DLScore execution, is it?

Thanks for your comments.
