I got the solution for the same issue from this Stackoverflow earlier(couple of months back) but I forgot it.
The solution should be like this: download the wrapt package from GitHub and placed the same in c: drive \ user profile location \wrapt.
while installing the tensorflow package, wrapt obstructing it
pip install tensorflow
error while installing the tensorflow
Installing collected packages: wrapt, tensorflow
Found existing installation: wrapt 1.10.11
ERROR: Cannot uninstall 'wrapt'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.
