   > I don't know if you're using example from _cpp-package/example/resnet.cpp_, but I couldn't run this example - I fixed it by replacing
   > `Xavier xavier = Xavier(Xavier::gaussian, Xavier::in, 2);`
   > with:
   > `Xavier xavier = Xavier(Xavier::gaussian, Xavier::out, 2);`
   > First run worked fine and net was learning, but second run shows similar issue with yours.
   > Probably it's problem with parameter initialization.
   > I fixed it by replacing:

   > ```
   >   //Xavier xavier = Xavier(Xavier::gaussian, Xavier::out, 2); <- Replace xavier with default Initializer
   >   Initializer init = Initializer();
   >   for (auto &arg : args_map) {
   >     std::cout << arg.first << std::endl;
   >     init(arg.first, &arg.second); // <- changed variable name

   Do you check-in the fix?
