Installing v0.14.0

[sstaszak]

Describe the bug
I am unable to install v0.14.0 due to errors with Cython:
Error compiling Cython file:
causalml/inference/tree/causal/_builder.pyx:61:56: Cannot assign type 'double' to 'int'

To Reproduce
Steps to reproduce the behavior:
pip install causalml==0.14.0

Environment (please complete the following information):

• OS: macOS
• Python Version: 3.8
• Versions of Major Dependencies:cython==0.28

Is there a better way to install a previous version? Also is there a way to install with tensorflow a previous version?

[jeongyoonlee]

It's rather a complex issue caused by a series of dependencies among causalml==0.14.0, scikit-learn, and Cython. The best way to address it is by installing causalml==0.14.1, where we removed the scikit-learn dependency (#686).

Is there any reason why you need to use the previous version?

Hi, @sstaszak, it is better to install the recent version or even to install the package from the main branch of the source code.

In case if you really need the previous version to be installed for some reason, you can do the following:

1. Clone the source code of v0.14.0: git clone --depth 1 -b v0.14.0 git@github.com:uber/causalml.git
2. Set the upper bound for Cython package version in pyproject.toml, see and build from source.

Yes! We need the previous version due to an issue with v0.14.1 being incompatible with our current model.

This is very helpful thank you! What if we want the option to install with TF because we are needing DragonNet

In this case run pip install .[tf] command in the source code directory.

@alexander-pv I still seem to be running into the cython issue even when I clone the source code of v0.14.0, set the upper bounds, and build from source:

[alexander-pv]

@sstaszak, please, try to install from source using clear python environment. I've just tested package building with freshly created python3.9 env. Everything works as expected. It seems that some package reinstalls Cython at the final stage of causalml installation.

You can also use whl from this archive: causalml-0.14.0-cp39-cp39-linux_x86_64.zip

The issue has no relations to causalml library. It is a networking problem with pip/urllib3. Related pip thread: pypa/pip#9972 I suggest creating new python environment and repeating package installation.

when I applied the below command:
pip install causalml@git+https://github.com/uber/causalml#egg=causalml

I received the below error:

error: subprocess-exited-with-error

× git clone --filter=blob:none --quiet https://github.com/uber/causalml 'C:\Users\Iman\AppData\Local\Temp\pip-install-e6wu5yao\causalml_f361080b3a7c4c87b7c278ea2188376c' did not run successfully.
│ exit code: 128
╰─> See above for output.

note: This error originates from a subprocess, and is likely not a problem with pip.
