Unknown error in Rtsne

[keoghca]

I'm trying to run a spectral initialization on Twitter data to find K in R. This is the EXACT same code I used about a year ago with no problem.

Here is the code and the error message:

tweet_lda <- stm::stm(tweetDTM,
K = 0,
verbose = TRUE,
init.type = "Spectral",
seed=1)

Error in tsneAnchor(Q, verbose = verbose, init.dims = settings$init$tSNE_init.dims, :
an unknown error has occured in Rtsne

I have also tried using the control parameter as suggested by someone else (#236) with no success. Would really appreciate any help!
