+The logo of DeePMD-kit is a beaver. Beavers were widely distributed in Europe and Asia but became nearly extinct due to hunting. Listed as a first-class state-protected animal in China, the population of beavers in China is less than the giant pandas. We hope that users of DeePMD-kit can enhance the awareness to protect beavers.
