You need to manually update pip with:
python -m pip install --upgrade pip
As per discussion on the issues page on Github
This issue should now be fixed in future versions of pip
Pull request on Github

This worked for me:
python -m pip install --upgrade pip

have you tried:
python -m pip install --upgrade pip
or
pip install --upgrade pip
Good luck

It's Just a Warning for upgrading the pip you can do it with any of these commands
python -m pip install --upgrade pip
or
pip install --upgrade pip

How do I upgrade from pip 1.0?

I was trying to install a package which required an older version of pip and (stupidly) thought it would be a good idea to try installing the oldest version of pip possible (1.0).
To clarify, it is not pip 1.0.1 (which most guides I found on the internet refer to), but pip 1.0
When I attempt to run 'python -m pip install --upgrade pip', I get the following error:
C:\mydirectory\venv\Scripts\python.exe: No module named pip.__main__; 'pip' is a package and cannot be directly executed
When I run 'pip --version', I get the following info:
pip 1.0 from c:\mydirectory\venv\lib\site-packages (python 3.7)
Is there any way I can upgrade pip from this point?

python -m pip install -U pip should work. That is how I do it.

Try this:
python3 -m pip install pip

python -m pip install --upgrade pip does not work

Upgrading pip does not do anything, just tells me to upgrade Pip again and that the requirements are satisfied--however, I am on an old pip version. This is Python27, I get the same issue whether I am in a virtual environment or not.
Output:
C:\Python27>python -m pip install --upgrade pip
Requirement already up-to-date: pip in c:\python27\lib\site-packages
You are using pip version 9.0.1, however version 19.1.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.
Versions Installed:
$ pip --version
pip 9.0.1 from c:\python27\lib\site-packages (python 2.7)

I think it how to update pip will help you and make sure that you are running command prompt as Administrator. you can do this by right click on the "Command Prompt" application and choose "Run as administrator" and type this command in your command prompt.
python -m pip install -U pip
try this if it isn't working for you..
Download Pip 19.1.1
Install Pip using this command
$ python -m pip install downloads/pip-19.1.1-py2.py3-none-any.whl
or if it is tar.gz file then
$ python -m pip install downloads/pip-19.1.1.tar.gz

python pip ask me to update but it is already updated

Every time I use pip to install some package, it says:
You are using pip version 10.0.1, however version 19.0.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.
But when I run
python -m pip install --upgrade pip
It says:
Requirement already up-to-date:
Why is this happening?

Based on your comments, pip is linked to your python 3 installation. The version of pip included in your python 2 installation is up to date (as shown by the python -m ... command you ran).
To update pip for python3, run the same command but using python3 instead. Something like
python3 -m pip install --upgrade pip
Given that the pip you are using is saying it needs updating, you could also just run
pip install --upgrade pip

pip is a package and cannot be directly executed

Im trying to install google assistant on my Raspberry Pi, but when I keep getting an error: pip is a package and cannot be directly executed

Instead of
pip [...]
Try doing
python -m pip [...]
Can't really help more without more info.

I think your version of pip is old. You need to upgrade it first, like this:
pip install -U pip
You may need to upgrade setuptools too:
pip install -U setuptools
Since google-assistant-library is available as a wheel, you need to install wheel too:
pip install wheel
I don't know if you can do that with Raspberry Pi, but I recommend you to used a virtualenv. That way, you have a fresh and isolated Python executable and a recent version of pip.
virtualenv your_proj
source your_proj/bin/activate
pip install wheel
pip install google-assistant-library

For newer version ie. using pip3:
pip3 install -U <<package name>>

I had the same problem.
I think it was an outcome of a failed
> .\python.exe -m pip install --upgrade pip
do to some environment misconfiguration.
So it first removed the existing version 10.0.1, and then the installation of the new version 22.3.1 failed, leaving me with no pip.
From official documentation, I ran
> .\python.exe -m ensurepip --upgrade
which restored the original pip 10.0.1.
Then I fixed the environment problem, and then again
> .\python.exe -m pip install --upgrade pip
I now have pip 22.3.1.
