Prebuilt-tenserflow version issue

[Harishrelysys]

Hi all,
We have a ARM 64 bit board on Renesas RZG2M processor for compiling r2inference we already have tensorflow(version-2.0) how to make use of this tensorflow instead of prebuilt-tensorflow in yocto.

R2Inference will look for the C API (instead of the C++ one). Do you have that one installed as well?

Hi michaelgruner,
We have already working tenserflow 2.0 yocto recipe so what we did is in r2inference recipe we gave DEPENDS = "tensorflow" but while configuring r2inference we are getting below error in yocto
