Model restoration

[YuchiSun]

The restoration part of the code written by @Charles-Gulian does not work on my computer.

Would like @Charles-Gulian to confirm that it indeed is capable of restoring models on his side.

@YuchiSun I just confirmed that the code still works on my computer... A few notes: (1) Make sure to run the preceding cells in the notebook before running the model re-loading cells (all preceding cells except "3. Model Training"). (2) My tensorflow version is 2.4.1 and my keras version is 2.4.0. I suggest making sure the packages on your machine are also up to date.

If you've already tried (1) and (2) then we can set up some time to try to debug?

Sure yeah let's set up some time. I've done the two steps you listed, so I'm pretty lost.

For the restoration code, did you use the code you were using back then, or are you using the code block commented out in the main branch? They should be equivalent but I want to rule out that factor. Can you test that?
