ERROR: spdlog error C2338: Cannot format an argument. To make type T formattable provide a formatter<T> specialization:

[SpaceView]

Thanks for your bug report. We appreciate it a lot.

win10 + VS2019
I use cmake-gui to generate the solution and then started to compile the file, and got the following problem,

currently I'm not sure whether this is a spdlog problem or a mmdeploy problem or both.
the only thing I'm sure is that this error is raised by the following sentence, in tensor.cpp.

MMDEPLOY_ERROR("mismatched data type {} vs {}", desc_.data_type, tensor.desc().data_type);

My temporary fix is make them integer,

MMDEPLOY_ERROR("mismatched data type {} vs {}", (int)desc_.data_type, (int)tensor.desc().data_type);

any better idea, please?

Can you share your way to build and install spdlog?

[xinsuinizhuan]

I meet the same error.

[irexyc]

The spdlog v1.9.2 should work.

@lzhangzz it seems mmdeploy failed to integrate the latest spdlog. Please investigate this issue.
