Hi, Thank you for your time and help with the issue.
It seems the package installation was successful. but
when I run tf$session(), it prompts the TF module is not found.

Not sure what has happened here.
so tried to see if the module could be accessed in python,
but it throwed up another error.

sorry I couldn't get much help searching online forums, tried to sort the error in different ways, but could not get it fixed. If there was similar situation addressed in this forum, please redirect me there.
Thanks again.

You could try a manual install of TensorFlow as per

https://www.tensorflow.org/install/

then test if it works in Python, and then if successful direct R to use that Python installation...

[skeydan]

Update: You seem to be running into problems as described here

tensorflow/tensorflow#11571

Perhaps any of the suggestions there can help you.

Also this script

https://gist.github.com/mrry/ee5dbcfdd045fa48a27d56664411d41c

checks TF install on Windows, and there are extensive discussions.
Perhaps you can get help there?
