Inf loss
Once the loss becomes inf after a certain pass, your model gets corrupted after backpropagating. This probably happens because the values in "Salary" column are too big. try normalizing the salaries. Alternatively, you could try to initialize the parameters by hand (rather than letting it be initialized randomly), letting the bias term be the ...
