Install USD pixar library

I have some trouble for installing USD library on Ubuntu. Here is the tuto I want to follow.
On github, I cloned the git, run the script build_usd.py and change the env var. But when I want to run this simple code
from pxr import Usd, UsdGeom
stage = Usd.Stage.CreateNew('HelloWorld.usda')
xformPrim = UsdGeom.Xform.Define(stage, '/hello')
spherePrim = UsdGeom.Sphere.Define(stage, '/hello/world')
stage.GetRootLayer().Save()
By changing the env var, eitheir the command "python " can't be found or the "module pxr" can't be found.
I tried to move the lib and include in my directory in usr/lib, ur/local/lib, usr/local/include but still pxr seems not to be found.
I am really confused about how to install and use library in general for python to found on ubuntu.

Pyinstaller and Django any collect_submodules failed to import

This problem is new to me.
When using extra libraries, they cannot be incorporated into the pyinstaller build.
As an example I tried using --hidden-import, --collect-submodules and added a hook-djoser.urls.py file to try to solve one of the other problems. In this file I did this.
hook-djoser.urls.py in Lib\site-packages\PyInstaller\hooks
from PyInstaller.utils.hooks import collect_submodules
hiddenimports = collect_submodules('djoser.urls')
# pyinstaller --noconfirm --onedir --console --name "royalback" "C:/Users/Shudf/royalback/manage.py"
And I can't make it work.
Would anyone be available to help?
Thanks

django.core.exceptions.ImproperlyConfigured: Requested setting

"Django deprecated" error in Django-Admin

When I am using django-admin startproject api then it is opening file name django-admin.py and the code looks like this :
#!C:\Users\Administrator\Desktop\api\venv\Scripts\python.exe
## When the django-admin.py deprecation ends, remove this script.
import warnings
from django.core import management
try:
from django.utils.deprecation import RemovedInDjango40Warning
except ImportError:
raise ImportError(
'django-admin.py was deprecated in Django 3.1 and removed in Django '
'4.0. Please manually remove this script from your virtual environment '
'and use django-admin instead.'
)
if __name__ == "__main__":
warnings.warn(
'django-admin.py is deprecated in favor of django-admin.',
RemovedInDjango40Warning,
)
management.execute_from_command_line()
I am using virtual environment. I am not getting how to get rid of it.

Short answer:
Use django-admin.exe instead of django-admin because django-admin.py is deprecated.
Example:
django-admin.exe startproject NEW_PROJECT_NAME
django-admin.exe startapp NEW_APP_NAME
Long answer:
If you use the command "where django-admin" (Windows) / "whereis django-admin" (Linux), you will see that there are probably two shortcuts.
In my case:
C:\Program Files\Python39\Scripts\django-admin.exe
C:\Program Files\Python39\Scripts\django-admin.py
I suppose that using an .exe extension file is faster than using the .py python extension file.
There may be another solution, I haven't tried to delete the file with "py" extension (django-admin.py), I just found that the fastest solution was to use "django-admin.exe startproject PROJECT_NAME", and so on.

The most straightforward way is probably to uninstall and reinstall Django in your virtual environment, if you're okay using the latest version of 3.2:
pip uninstall Django
pip install 'Django<4'

git executable not found in python

I was trying to clone a git repo with access key, but when I am trying to run it, It throws an exception saying git executable not found.
But i have installed git and the in_it.py shows correct path "C:\Program Files\Git\bin" Also I have installed gitpython to use the library in python
here's my code...
import git
git.Git("D:/madhav/myrep/").clone("#github.com:myrepo/scripts")
========= and it throws the following exception =================
Traceback (most recent call last): File
"C:\Users\1096506\Desktop\gitclone.py", line 1, in <module>
from git import Repo File "C:\Users\1096506\AppData\Local\Programs\Python\Python36-32\lib\site-packages\git\__init__.py",
line 84, in <module>
refresh() File "C:\Users\1096506\AppData\Local\Programs\Python\Python36-32\lib\site-packages\git\__init__.py",
line 73, in refresh
if not Git.refresh(path=path): File "C:\Users\1096506\AppData\Local\Programs\Python\Python36-32\lib\site-packages\git\cmd.py",
line 293, in refresh
raise ImportError(err) ImportError: Bad git executable. The git executable must be specified in one of the following ways:
- be included in your $PATH
- be set via $GIT_PYTHON_GIT_EXECUTABLE
- explicitly set via git.refresh()
All git commands will error until this is rectified.
This initial warning can be silenced or aggravated in the future by setting the
$GIT_PYTHON_REFRESH environment variable. Use one of the following values:
- quiet|q|silence|s|none|n|0: for no warning or exception
- warn|w|warning|1: for a printed warning
- error|e|raise|r|2: for a raised exception
Example:
export GIT_PYTHON_REFRESH=quiet

I had the same issue. What I did is:
I went to: System Properties -> Environment Variables
On System Variables Section I clicked Path, Edit and Move Up.
Environment Variables
Edit and Moved Up two places from the bottom

Error occurs because git is not in the path. So its not able to import git module.
Couple of ways to resolve it.
As suggested above adding the git binary path to environment variable path.
If git is not being used directly in the module and its only a dependent module import thats throwing this exception before importing git we could add
os.environ["GIT_PYTHON_REFRESH"] = "quiet"
and import git after this line, this would suppress the error caused due to git import

Had the same problem got it to work thanks to Muthukumaran. Just make Muthukumaran answer more clear.
Follow these steps:
import os
os.environ["GIT_PYTHON_REFRESH"] = "quiet"
import git

See if you have installed Git in the OS.
If not install git first this will solve your error.
Centos
sudo yum -y install git
Ubuntu/Debian
sudo apt-get install git
Mac Os
sudo brew install git
This solved my problem.

Make sure you're not in an inaccessible directory on *nix, such as when you've just been root and then done a su username
you may still be in root's home folder and that will trigger this error (assuming you have the correct environment variables set, and have sourced the .profile or .bashrc etc with source ~/.bashrc )
which git
/usr/bin/git
I was getting this error even after setting the environment:
in ~/.bashrc
# for bench
PATH=$PATH:/usr/bin/git
export PATH
GIT_PYTHON_GIT_EXECUTABLE=/usr/bin/git
export GIT_PYTHON_GIT_EXECUTABLE
cd
and it's working
$ bench --version
WARN: Command not being executed in bench directory
5.3.0

I came across similar problem recently and installing git followed by restarting Windows Powershell CommandLine solved the problem. May it helps.

For those who are using a Lambda layer with it. It worked adding as the comment above says just adding GIT_PYTHON_REFRESH=quiet as an environment variable.

Execute GIT_PYTHON_REFRESH=quiet in your terminal and then try to run the code.

Python GEOS ImportError

I'm getting this error:
ImportError: Could not find the GEOS library (tried ""geos_c"", ""libgeos_c-1"").
Try setting GEOS_LIBRARY_PATH in your settings
when I run:
from django.contrib.gis.geos import *
pnt=GEOSGeometry('POINT(23 5)')
print(pnt)
I added GEOS_LIBRARY_PATH = 'C:/Python34/Lib/site-packages/osgeo/geos_c.dll'
in C:\Python34\Lib\site-packages\django\conf\project_template\project_name\settings.py
But still Im getting the same error. How to solve this?

I don't know what is the most correct way to use with Windows, you can try to find solution here, but for ubuntu command:
sudo apt-get install binutils libproj-dev gdal-bin
solved the problem.
P.S. From dock:
The setting must be the full path to the C shared library; in other words you want to use libgeos_c.so, not libgeos.so.
Extension of the library must be *_c.so

Are You sure path is correct? This is My path:
GEOS_LIBRARY_PATH = 'c:\\Program Files\\PostgreSQL\\9.1\\bin\\libgeos_c-1'
You need GEOS from PostgreSQL.
