Hello R family. Please I have created this topic because i could not find any solutions in similar topics. I am having trouble installing and using tensor flow again . I had previously installed it successfully, but after starting a new R session and I tried to install it again, I get all of these, including an error message:
install_tensorflow()

Does it have anything to do with anaconda installation? The anaconda application on my machine got corrupted and I removed it. Do I need to install miniconda through reticulate? Please, as always, your helpful suggestions are highly appreciated. Thanks
