Therefore, on the older version of TensorKit.jl, use the following code to save the data TensorKit.jl is a package that provides types and methods to represent and manipulate tensors with symmetries.
user_offset = np.array(self.user_feat_offset).reshape(1, len(self.user_fields)) item_offset = np.array(self.item_feat_offset).reshape(1, len(self.item_fields)) with ...
