Observation = None and done = True when using from_file method

[rezabayani]

Hi,

My Ecole (v8) is having trouble reading observations from the optimization model stored as mps file. Basically, it returns None observation and True done flag when I reset the environment. I did the same approach with Ecole v7 and it was okay back then. Interestingly, when I tried feeding other mps files found online, it is okay with some of them and not with others. I have attached 2 images. Number 1 is when Ecole is acting as intended, using an mps model found online. Number 2 is when Ecole is acting funny, with an mps file I generated myself and was okay with Ecole v7.
