Issue after installation of shap with shapper

[avishek-ghosh]

Hi,
In linux suse SLES 15 sp1 set up, I already had created a virtual environment and installed R and tensorflow .
I had a tensorflow model and I could successfully load the model in R.
But when I installed shapper successfully, then with library(shapper), installed shap with command shapper::install_shap(); after that I am getting error tensorflow not found while loading the tensorflow model. Please help. Please let me know if any more information is needed.
Also, I did not find a deep explainer in shapper which seems only available in shap ? if it is not true can you point me to the right implementation?

TF version - 2.4.1 shapper - 0.1.3 shap - 0.39.0
Regards,
