Error while running the example

[lilingnan]

Hi,I like the function of cppflow very much, but I encountered an error when I tried to run an example after installing, and it didn't work even after updating the gcc version to 9.4.0.Do you know what is the reason?

error was:
main.cpp: In function ‘int main()’:
main.cpp:45:30: error: could not convert ‘input’ from ‘cppflow::tensor’ to ‘std::__cxx11::string {aka std::__cxx11::basic_string}’
auto output = model(input);
^
main.cpp:49:35: error: expected primary-expression before ‘float’
auto values = output.get_data();
^~~~~
main.cpp:51:19: error: unable to deduce ‘auto&&’ from ‘values’
for (auto v : values) {

thanks,
li

Hi!

Can you provide a complete example of what you are trying to do? With just two lines of code is difficult to tell.

On thing that I see is that you are not telling your datatype when using get_data, it should be something like output.get_data<float>().

Hi! thank you for replying me! I just tried the simple example that you offered to us:

#include <cppflow/ops.h>
#include <cppflow/model.h>

// C++ headers
#include

int main() {
auto input = cppflow::fill({10, 5}, 1.0f);
cppflow::model model(std::string(MODEL_PATH));
auto output = model(input);

std::cout << output << std::endl;

auto values = output.get_data<float>();

for (auto v : values) {
    std::cout << v << std::endl;
}
return 0;

}

and "auto" reports an error as "explicit type is missing("int" assumed)

thanks,
li

Is that the only code you are using?

Could you post the complete error you getting?

[lilingnan]

Yes, only this one

main.cpp: In function ‘int main()’:
main.cpp:45:25: error: could not convert ‘input’ from ‘cppflow::tensor’ to ‘std::string’ {aka ‘std::__cxx11::basic_string’}
45 | auto output = model(input);
| ^~~~~
| |
| cppflow::tensor
main.cpp:49:35: error: expected primary-expression before ‘float’
49 | auto values = output.get_data();
| ^~~~~

It looks like the compiler is not finding the MODEL_PATH var. Check if it's declared in the CMakeLists.txt, or change the path directly in the code:

cppflow::model model(std::string("/path/to/model"));

Thank you so much for replying me patiently, the problem has been successfully solved! thanks and happy new year!
