Attempting uninstall: wrapt
Found existing installation: wrapt 1.11.2
Uninstalling wrapt-1.11.2:
ERROR: Could not install packages due to an EnvironmentError: [WinError 5] Access is denied: 'c:\\programdata\\anaconda3\\lib\\site-packages\\wrapt-1.11.2.dist-info\\INSTALLER'
Consider using the `--user` option or check the permissions.
Can anybody tell me the solution of this?

pip uninstall python 3.8.4
This command will never work. pip is a python package manager, i.e. for an installation of python, pip is responsible to install modules to that python installation. It does not manage the installation of python itself
To your error with the tensorflow installation:
pip install tensorflow
and
ERROR: Could not install packages due to an EnvironmentError: [WinError 5] Access is denied: 'c:\\programdata\\anaconda3\\lib\\site-packages\\wrapt-1.11.2.dist-info\\INSTALLER'
This is caused by the fact that the c:\\programdata is write protected from non-admin users, so in order for your command to succeed, you should run your cmd as admin.
BUT:
It seems like you have installed anaconda and are trying to install tensorflow into the base environment using pip. Pip in turn tries to uninstall some already existing package, probably to fulfill the tensorflow requirements. But the already existing package are probably installed by conda when you first installed anaconda, so you ware getting into dangerous waters here and you are risking to break your base environment, so two suggestions:
Create a new environment conda create -n tf tensorflow-gpu
Use conda commands to install tensorflow. conda install tensorflow-gpu will give you tensorflow
To your other question:
How to downgrade python
The solution is also to use a conda command:
conda install python=<some version>
or, even better, simply create an environment with the version you need:
conda create -n py37 python=3.7
would for example give you an environment called py37 with python3.7 installed. It can be activated and used with
conda activate py37

Will not install to the user site because it will lack sys.path precedence to setuptools in /tensorflow/venv/lib/python3.6/site-packages

I did some more digging.
Apparently the virtualenv was created using sudo so I needed to alter permissions.
Details here:
How to avoid "Permission denied" when using pip with virtualenv
to be specific it was
sudo chown -R your_username:your_username path/to/virtuaelenv/

matplotlib 1.3.1 has requirement numpy>=1.5, but you'll have numpy 1.8.0rc1 which is incompatible.

I was able to solve this with #Jacob's solution with some additional steps. I'll post it here for anyone else facing this.
Firstly as Jacob mentioned I downloaded and installed the latest Python 2.7.14+.
Executed sudo easy_install pip to install pip again
Executed sudo pip install numpy

Download the latest version of Python 2.7 (https://www.python.org/downloads/), matplotlib install should work fine after that.
Also if it's a brand new mac, just make sure that you have command line tools installed

Installing PyInstaller on Mac

I have not seen this issue in my google searches. I am trying to install PyInstaller on my work Mac which I do not have administrative access.
$ pip install --user pyinstaller

Successfully installed pyinstaller-3.3.1
The install seems successful, however...
$ pyinstaller
-bash: pyinstaller: command not found
I checked my PATH
$ echo $PATH

What am I missing here?
Thanks for reading.

I had to install the tar.gz file from here:
http://www.pyinstaller.org/downloads.html
Then it can be run from the extracted folder.
$ python pyinstaller.py script.py

On my Mac pip installed the binary in /Users/%Username%/Library/Python/2.7/bin. If you add that to your PATH it should work.
