Perplexity: 20 Learning rate: 10 N_iters: 250

tensorboard returns a scatter plot like this: enter image description here

sklearn tSNE returns a scatter plot like this:

enter image description here

The data is the exact same. What am I doing wrong?

My guess is you're not doing anything wrong. The algorithm depends on a random starting point, so two runs of the same algorithm will produce different results, unless you fix the seed of the random number generator.

In this case you're comparing two different implementations, so who knows... Neither of the results has any clear structure that the other is lacking, so I have no reason to think anything is wrong.
