python quantile LINEAR regression by using Deep neural networks

do it for all main Deep NN packages
keras
tensor flow
fast.ai
pytorch

then it should be 4 solutions, all of them should provide good performance

data is mixture of categorical and continues features
at least 5 categorical features
at least 5 continues features
at least 100000 rows
data you find : several datasets ( more than 2)

see
primitive linear (or log-linear) model W \cdot \mathbf{x} + \mathbf{b} (where W is a weight matrix, \mathbf{x} = (x_1, x_2) is an input vector, and \mathbf{b} is a bias vector) without hidden layers,

better to find and use existing code from web

to prove all done correctly: make prediction manually use only one dimension vector coefficients

coef_ : ndarray of shape (n_features,) or (n_targets, n_features)
Weight vector(s).
