I am running the command pip install django-observer
Thank you for your help

This django-observer package hasn't been maintained for a long time. The github repository states it works on Python 3 version 3.2 and 3.3 though. So you might have luck setting up a virtualenv with python 3.2 or 3.3 and working from there.
The package appears to have done work similar to that of Django Signals. You can read up on them here. Signals are an implementation of the Observer pattern.
Just FYI, I tried installing the package too and got the same error on my MacOS machine. This is why I suggest switching to Signals.

In another forum, I read that this is a cython issue, I have uninstalled and reinstalled it, and it did not work out. I am working with Python 3.6.10, and here are the versions of the dependent packages on my system.
setuptools= 50.3.0
pip=20.3
numpy=1.18.5
scipy=1.4.1
matplotlib
pandas=1.1.2
scikit-learn=0.23.2
statsmodels=0.12.0
seaborn
Cython=0.29.21
xgboost
pydotplus
tqdm
shap
dill
lightgbm
pygam
packaging
keras
tensorflow=2.3.0
I checked the dependency requirements, and I believe all the above packages are acceptable for installing causalml. I also tried cloning the git repo and installing it, and I got the same error. Your feedback and suggestion are greatly appreciated.

Google App Engine rtree Python Module Installation

Google App Engine, does not include libspatialindex, and hence I am unable to install rtree python module, even if it is in requirements.txt,
it gives following error, while deploying app. ( app works fine locally. ) How do I install specific lib in python standard google app engine environment ? or How do I request them to do so ?

You will need to use flexible environment with custom runtime to utilize packages not preinstalled in standard environment.
To install libspatialindex, add this to the Dockerfile:
sudo apt-get update -y
sudo apt-get install -y libspatialindex-dev

Then I need to manually install them and it is just unconvenient.
python script.py # ModuleNotFoundError: No modul named 'dateutil'
And I really dont know what I am making wrong. My Goal is after Cloning and installing to the venv it should work but it doesnt work.
