Loading data from .csv file

[GearFear]

I try to load data from mlsd datasets for k-means clustering on GPU.

I call:
val (mm, opts) = KMeans.learner("data/MLSD/mlsd1_4898430_38_20.csv")
opts.dim = 20
opts.batchSize = 20000
opts.nend=10

mm.train

And I get following error:

Even if I change the extension of file to .txt, I still have this error.
I use scala interpreter using ./bidmach

I have 2 Tesla K80.

If I load data from MNIST8M folder, I can use clustering with this data successfully.

But I'd like to get the power of BidMach to cluster my own datasets. How can I use it in BidMach?

Thanks in advance!
