As title says.
Default behavior of arctic model produces shape issues with AutoTP due to the MLP layer performing
w2 * act(w1*w3). However, method provided to fix Mixtral-7x8b in #5257 does not work since the MLP for Arctic is also used within a ModuleList for the MoE. This results in MLP weights hiding behind individual experts as layers#.w#, which is not caught by the fix in #5257. This adds the check directly within replace, where it can check for actual layer names for thew2key in the model to patch withall_reduce.
