Hi @andrewjlee0,

Good catch. The n_dim argument has been removed (commit 3e49e236ce30f104257a97a8fe8514ca2de37a2f) since it is redundant with the free parameter alpha. Originally this was included to help users pick a reasonable default (i.e., van der Maaten suggests alpha=n_dim-1). This decision is now left up to the user.
