APIs taking string arguments will be deprecated in future releases. Use APIs taking non-string arguments instead.

Status GetVariables(const std::vector<std::string> &var_names, std::vector<Tensor> &var_values)
Status GetVariables(const std::vector<AscendString> &var_names, std::vector<Tensor> &var_values)

Parameters
