FFM SetTXTModel forgets a delimiter between parameters

[kcstokely]

From the docs: "For FM and FFM, we store one vector of the latent factor in each line."

Right now this outputs:

0.156129 0.223862 0.114672 0.1005360.103618 0.100097 0.314356 0.0808605

This is an output of the model txt file for a FFM with 2 fields and 4 latent features. Notice there is a space missing between the 4 latent values for field #1 and the 4 latent values for field #2.

EDIT: This is using the Python API.

@kcstokely Thank you so much. We will fix this problem.

I update the model output like this, you need to git clone the source code and re-build it:

Linear:

bias: 0 i_0: 0 i_1: 0 i_2: 0 i_3: 0

FM:
