Quick Fix: To solve the "AttributeError: cython_sources" issue while installing catboost==1.2.2, use one of these workarounds:
Preinstall cython<3, then install pyyaml without build isolation, followed by installing other dependencies.
Alternatively, create a constraints file to force pip to use cython<3 at build time.
Refer to the GitHub issues (links provided) for more details and updates.
The Problem:
I’m trying to install ‘catboost==1.2.2’ using pip, but the installation fails with errors related to missing attributes during wheel building. The build process seems to be unable to find files in the ‘cython_sources’ attribute, resulting in an ‘AttributeError: cython_sources’. The issue persists despite trying various methods to install the package.
The Solutions:
Solution 1: Preinstall Cython
One way to resolve this issue is by pre-installing Cython with a version less than 3.0.0. Here’s how you can do it:
Open your terminal or command prompt.
Run the following command to install Cython version 2.x:
pip install "cython<3"
After Cython is installed, try installing catboost again:
pip install catboost==1.2.2
This should bypass the error related to cython_sources and allow catboost to be installed successfully.
Solution 2: Use a Constraints File
Another approach is to use a constraints file to force pip to use a specific version of Cython during the installation of catboost. Here’s how to do it:
Create a new file named constraints.txt in a convenient location on your computer.
Open the constraints.txt file and add the following line:
cython<3
Save and close the constraints.txt file.
Now, install catboost using the following command:
Replace /path/to/constraints.txt with the actual path to the constraints.txt file you created in Step 2.
By using the constraints file, you’re instructing pip to use a version of Cython less than 3.0.0 during the installation of catboost. This should resolve the cython_sources error and allow catboost to be installed successfully.
Q&A
I am facing error in installing catboost==1.2.2. The error is AttributeError: cython_sources
—
The error is likely related to PyYAML and Cython.
What is the possible solution to the error AttributeError: cython_sources
—
There are two potential workarounds:
Preinstall cython<3.0.0, install pyyaml without build isolation, then install remaining dependencies.
Use a constrains file to force pip to use cython<3 at build time.
Is there a specific GitHub thread I can refer to for more details?
