- Use 3.8 for Linux - Use 3.9 for Windows
- scikit-learn is dropping support for `np.matrix` which is what we get from `todense()`, so we need to use `toarray()` instead.
- The old default `squared_loss` has been deprecated and renamed to `squared_error`.
- Scikit-learn v1.0 will be deprecating the `normalize` attribute for linear models - This attribute is set to `False` by default in most scikit-learn linear models anyway and so no warnings are surfaced in SKLL. - However, for `Lars`, the default value of `normalize` is still set to `True` and so we need to force it to False to avoid deprecation warnings. - This code will actually lead to an execption in the `_create_estimator()` method when the `normalize` attribute doesn't exist, so that will be the perfect reminder to excise this if block entirely when the time comes.

Good catch! I will modify it to be the same as the requirements files. |

This PR closes #699.
This change is pretty straightforward but it’s definitely backwards incompatible which we will reflect in the release version when we put together the release.
The change specifically motivated by the upgrade are:
requirements.txtandconda_requirements.txtto point to the latest scikit-learn (v1.0.1) and allow up to v1.0.2.squared_erroras the default value of thelossparameter forRANSACRegressor.toarray()for converting sparse numpy arrays to dense instead oftodense()since the latter returns annp.matrixinstead of annp.ndarray.
