Tensorflow Warning - Could not load dynamic library 'cupti64_101.dll'; dlerror: cupti64_101.dll not found

I've seen other similar issues related to cupti dll error. However, the answer seems to be that the dll location needs to be in the path. Well, my dll is in the path. The warning listed in the title is followed by several errors related to the fact that the cupti dll was not loaded. 

(venv) PS D:\Projects\tensorboard> $env:path -split ";" 
D:\Projects\tensorboard\venv/Scripts

Tensorflow 2.2.0
Tensorboard 2.2.1
cuda toolkit 10.1

Here is a snapshot of a couple of the warning/error messages. Several more followed these.

Providing the solution here (Answer Section), even though it is present in the Comment Section, for the benefit of the community.

There is no cupti64_101.dll file presented at C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.1\extras\CUPTI\libx64.

Due to this Could not load dynamic library 'cupti64_101.dll'; dlerror: cupti64_101.dll not found warning has appeared when ever trying to run Tensorflow.

Once cupti64_101.dll copied to the above location, issue has resolved.
