Type map issue in DeepmdData #920
Description
type map may be wrong in init of Deepmddata
In the init function of Deepmddata class, it read type.raw and cast it from local type map (which is read from a system's type_map.raw) to the global type map which is defined in the input.json file. The code is below:
However, for example, in the Al Cu Mg alloy case, the global type map is [Mg, Al, Cu]. If a system only have one elements Al, and the local type_map.raw is [Al]. After process of init, self.type_map would be [Mg], which is incorrect logically.
my deepmd-kit version is v2.0.0.b3, and I print out the type map before and after init cast to identify want I'm trying to say.
