cppFlow and tensorflow 2
I used cppFlow for TF2 and got following error. Does it support tensorflow 2?
#include "../../include/Model.h"
#include "../../include/Tensor.h"
#include <opencv2/opencv.hpp>
#include
int main() {
// Create model
Model m("../model.pb");
}
Error LNK2019 unresolved external symbol "public: __cdecl Model::Model(class std::basic_string<char,struct std::char_traits
-
Yes, tf2 is supported

Your issue seems to be a linking problem with cppflow.
Yes, as @ljn917 commented, it looks like a linking problem.
Which TensorFlow C package are you using? and, how are you compiling and linking your code?
@serizba I met the similar linking error when I'm compiling the example project "load_model". I followed the instruction and used cmake to generate the Visual Studio project. When I'm trying to use VS2019 on Windows 10 to build the project I got the following linking error:

I've already add the path of tensorflow.dll and tensorflow.lib to the system PATH and the project's settings in VS 2019 as well:
Am I missing something? I really need some help.
Hi, @Bennett-Yang , I got a similar problem as yours, but I use the CPU version. I just wanna know have resolved your problem?

Sorry, I'm no longer working on the project I mentioned above. I still have no solution to this problem.
