Reuploading fix

[AdrianPerezSalinas]

I have solve the issue with the saved_parameters.pl file from the reuploading example.

What I did is essentially add some code such that:

• It tries to read the file and stores the contain as data
• If it is not, then an empty dict is created as data = {}.

Then the code looks into data for parameters. If it is found, the figures are painted. If it is not, and we do not mind whether it was because the file did not exist or because this calculation was never done, then the optimization is performed. Afterwards it dumps data into the file in any case.

Let me know if this solves your problem

@jubaglio let me talk to you in this PR. IN response to #397 (comment)

I am sorry, if does not work because of my fault, I did not check it properly.

I have added the following:

        try:
            data[dataset][layers] = parameters
        except:
            data[dataset] = {}
            data[dataset][layers] = parameters

The problem is that it is not possible to create a dict inside something that does not exist. For this reason we must add a previous step. You were completely right. However, I did it in such a way that it is not necessary to create all the list of dataset, and then we do not have to change it if we add more examples.

I think you can avoid this by making sure e.g. in line 30 that data[dataset] is not empty / not defined.
