[Question] An error occurs while installing autosklearn

[yevIbrahimov]

I try to install auto-sklearn to google colab using command !pip3 install auto-sklearn but I receive such log

It leads to error when I try to use autosklearn module import autosklearn.classification ModuleNotFoundError Traceback (most recent call last) in <cell line: 2>() 1 import numpy as np ----> 2 import autosklearn.classification 3 from sklearn.model_selection import train_test_split 4 from sklearn.linear_model import Perceptron 5 from sklearn.neural_network import MLPClassifier

I'm not exactly sure, but it looks like it's failing when building scikit-learn 0.24.2. You can checkout #1675 for a workaround.

@yevIbrahimov, which Python version do you use?

I had issues with both Python 3.10 and 3.11 and could install it to a Python 3.9-based environment.

[yevIbrahimov]

@GegznaV I use python 3.10, but switching to 3.9 version still does not help me with this issue

[yevIbrahimov]

@AmirAlavi I tried to use these steps to solve this issue but I still get an error !pip install Cython==0.29.36 !pip install scikit-learn==0.23 --no-build-isolation Restart runtime !pip install auto-sklearn

[GegznaV]

I use Ubuntu (via WSL on Windows 10) with Conda as Python's virtual environment manager. Before the installation of auto-sklearn, there was nothing in the environment except Python and the dependencies requested by the Conda installer.

Actual steps I took are described here (assuming that Conda is installed):

For python 3.10: Install these packages line by line solve this problem: scipy==1.8.1 Cython==0.29.35 scikit-learn==0.24.2 --no-build-isolation

For python 3.10: Install these packages line by line solve this problem: scipy==1.8.1 Cython==0.29.35 scikit-learn==0.24.2 --no-build-isolation

works for me

@whoisltd Hi Dat, it still cannot work on my colab.

[whoisltd]

@stupidoge Not sure but on google colab, may you need to restart runtime when you change or reinstall new package version
