<p>There is a "no such file" - error, but I don't think it comes from me. I am pretty that I have labels for every state and I don't get invalid label errors.<br>
Here are my files:<br>
<a href="https://github.com/mlpack/mlpack/files/42512/observationPKM.csv.txt">observationPKM.csv.txt</a><br>
<a href="https://github.com/mlpack/mlpack/files/42513/labels.csv.txt">labels.csv.txt</a></p>
<p>(you will have to delete the .txt extension)</p>
<p>How many samples are about "enough" samples? I just run with 4000. I will get some more but I don't think I will have more than 50k. Will that be enough to do some more gaussians?<br>
Greetings<br>
