umap.UMAP accepts strings as n_neighbors and min_dist, causing later failures

[conchoecia]

Hello, when I run this code, it does not fail.

>>> import umap
>>> n_neighbors = "5"
>>> min_dist = "0.01"
>>> reducer = umap.UMAP(n_neighbors = n_neighbors, min_dist = min_dist)
>>> 

The problem is that when I try to fit the data, I get an error:

mapper = reducer.fit(df.to_numpy())

results in '<' not supported between instances of 'numpy.ndarray' and 'str'

It would be nice if umap.UMAP enforced a type float or int for the variables n_neighbors or min_dist to avoid failing later without a clear error message. Thank you!
