~DeepPot()¶
-
DeepPot(const std::string &model, const int &gpu_rank = 0, const std::string &file_content =
"")¶ DP constructor with initialization.
- Parameters
model – [in] The name of the frozen model file.
gpu_rank – [in] The GPU rank. Default is 0.
file_content – [in] The content of the model file. If it is not empty, DP will read from the string instead of the file.
-
void init(const std::string &model, const int &gpu_rank = 0, const std::string &file_content =
"")¶ Initialize the DP.
- Parameters
model – [in] The name of the frozen model file.
gpu_rank – [in] The GPU rank. Default is 0.
file_content – [in] The content of the model file. If it is not empty, DP will read from the string instead of the file.
-
void print_summary(const std::string &pre) const¶
Print the DP summary to the screen.
- Parameters
pre – [in] The prefix to each line.
