Resolving error while installing devstack train on ubuntu

I am trying to install devstack train on ubuntu and get the following error:
ContextualVersionConflict: (glance-store 0.28.1
(/usr/local/lib/python2.7/dist-packages),
Requirement.parse('glance-store>=1.0.0'), set(['glance'])) You are
using pip version 9.0.3, however version 21.2.4 is available. You
should consider upgrading via the 'pip install --upgrade pip' command.
I did try upgrading pip using:
sudo apt-get install python-pip
sudo pip install --upgrade pip
But when I ran ./stack.sh again, I face the same issue.
Can you please let me know how can I resolve this issue?

I think the really true error reason is: Requirement.parse('glance-store>=1.0.0'),
Try this:
sudo pip install glance-store==1.0.0
the version 1.0.0 should replace by what you need.

Failed to install NumPy Package

This is because of a mismatch between your version of pip and numpy. See answer. Thus, first you must upgrade your pip:
On Linux or macOS:
pip install -U pip
On Windows:
python -m pip install -U pip
Once pip is updated, you may install numpy.

PyInstaller failing to install through pip

pip 19.0.1 from c:\users\halzein\appdata\local\programs\python\python37\lib\site-packages\pip (python 3.7)
Trying to install PyInstaller with this command:
pip3 install PyInstaller --trusted-host pypi.org --trusted-host files.pythonhosted.org
(I get errors if I try to use pip without trusted-host tags)
And the install keeps failing due to this error after downloading and installing build dependencies:
ModuleNotFoundError: No module named 'PyInstaller'
Command "c:\users\halzein\appdata\local\programs\python\python37\python.exe c:\users\halzein\appdata\local\programs\python\python37\lib\site-packages\pip\_vendor\pep517\_in_process.py get_requires_for_build_wheel C:\Users\halzein\AppData\Local\Temp\tmpfwtrnagf" failed with error code 1 in C:\Users\halzein\AppData\Local\Temp\pip-install-thcvcr0q\PyInstaller\
Not really sure what's causing this, and my searches have come up with nothing.

I faced same error, here's what worked for me:
Run windows powershell as administrator, and downgrade pip to 18.1 by typing pip install pip==18.1 this will uninstall 19.0.1 and install 18.1 version. After that just run pip install pyinstaller and it should finish it with no errors. Than you can upgrade pip to 19.0.1 with python -m pip install –upgrade pip
Hope this help you too.
Cheers =)

pip install tensorflow throw error when it try to install related packeg:futures

Environment: python 3.6.2
When I try to install tensorflow-gpu with this command:
pip3 install --upgrade tensorflow-gpu
It throws an error message when it tries to install related packeg:futures
Unknown requires Python '>=2.6, <3' but the running Python is 3.6.2.
But futures is python2 only package.
How can I handle it?

I find the issue in github :
https://github.com/tensorflow/tensorflow/issues/16478
it should install futures first:
pip3 install futures==3.1.1

You can download the source from pypi futures-3.2.0.tar.gz and install.
