I am a little puzzled when running ResPRE

Dear scholar,
hello!I have some problems when running ResPRE.
I run the following command:
python respre.py test/T0759-D1.aln test/T0759-D1.out 、
Then the console displays:
--------------------------------------------------------------------------------------
cuda is ready? : True
/media/ubuntu/619b7769-bf19-45af-9e3e-90232241302c/home/ubuntu/terence/ResPRE/precision.py:40: UserWarning: genfromtxt: Empty input file: "test/T0759-D1.out.weight"
weights=np.genfromtxt(weightfile).flatten()
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> [100%]
--------------------------------------------------------------------------------------
I have 2 questions:
1.What is the effect of this file (T0759-D1.out.weight)?
2.It reminded that file T0759-D1.out.weight was Empty input file. Does this affect the prediction results?
Hope you can give me the answer, thank you very much!
