I have been working on a project with fmrifMRI data. It has a training set of 300 * 21764$300 \times 21764$. I am working in python and have used lasso on it for feature selection. 

For different values of the hyperparameter it sometimes selectselects more than 300$300$ features, is that possible for lasso? Or does sci-kit not use the standard lasso?

Is number of features selected by lasso bounded by number of samples in the dataset?
