OSError when trying to import a sklearn dataset into Jupyter Notebook-CodePudding

With the code below:

from sklearn.datasets import fetch_california_housing
housing = fetch_california_housing()
housing

I get the error:

    OSError                                   Traceback (most recent call last)

OSError: [WinError 193] %1 is not a valid Win32 application

On my machine I have both Python 32 and 64 bit installed, so I am assuming the issue is that Jupyter Lab, where I am running the code, is mismatching the version of python on my machine and the version sklearn uses, causing the issue?

I have had no issues with sklearn or using Jupyter Notebook for analysis prior to this.

How do I read in the sklearn Real life dataset with no error, I am using Windows?

CodePudding user response：

I have now solved this. I had two versions of Python installed, one in my Anaconda path and one I downloaded on my machine directly. The machines version was 32 bit, Anaconda 64 bit so I deleted the 32 bit version as my computer is 64 bit, plus I was using the Anaconda environment.
