Release Mode: Application Crash

[vinaykumarngitub]

While executing the training functionality, the debug mode works fine. But in release mode, I am getting the following error:
Unhandled exception at 0x00007FFE1D4E9159 in .exe: Microsoft C++ exception: std::basic_string<char,std::char_traits,std::allocator > at memory location 0x0000007F726FF598.
