Recover saved Flux model from Julia 1.0 in Julia 1.1 #40

Open MaximeBouton opened 5 years ago

Hi, I have saved a trained Flux model in julia 1.0 a while ago and would like to retrieve it in julia 1.1 but I am getting the following error:

julia> BSON.load("model_car_1.bson")
ERROR: BoundsError: attempt to access Core.TypeofBottom

In julia 1.0 I can load the model fine. I have the same version of Flux (v0.7.2) and BSON (v0.2.1) on both installations. This is I believe the versions that were used to train and save the old model.

Do you have any suggestions on how to load the model without error in julia 1.1? Thanks
