to_arraymethod is added inversion 2.9in order to returns the confusion matrix in the form of a NumPy array. This can be helpful to apply different operations over the confusion matrix for different purposes such as aggregation, normalization, and combination. >>> cm.to_array() array([[3, 0...

For operations that don't, you can use rx_exec to deliver your code in a remote compute context. In this example, no raw data had to be transferred from SQL Server to the Jupyter Notebook. All computations occur within the Iris database and only the image file is returned to the ...

At the base of the stack are libraries that provide fundamental array and matrix operations (NumPy), integration, optimization, signal processing, and linear algebra functions (SciPy), and plotting (Matplotlib). Other libraries that build on these to provide more advanced functionality include Pandas...
