Entropy is 0 in every cell #149

Hello!

When I plot palantir_entropy I get 0 entropy across all the cells in my dataset. What am I doing wrong?

This can happen, e.g., if there is only one cell fate. Since, the cell-fate probability distribution is the same for all cells (1 for the only existing fate) the entropy for this distribution is constant as well.
