trimap: Illegal instruction error

Hi, I just installed TriMap and its dependencies (from conda). I ran the NIST demo script:

import trimap
from sklearn.datasets import load_digits
digits = load_digits()
embedding = trimap.TRIMAP().fit_transform(digits.data)

but on running the trimap command, I get the following error:

TRIMAP(n_inliers=10, n_outliers=5, n_random=5, distance=euclidean,lr=1000.0, n_iters=400, weight_adj=500.0, apply_pca=True, opt_method=dbd, verbose=True, return_seq=False)
running TriMap on 1797 points with dimension 64
pre-processing
Illegal instruction (core dumped)

Can you give me some advice on how to debug this? I attached my conda environment (conda_env.txt), if that helps. I’m excited to give this a go!

Many thanks and kind regards, Tim

Dear Ehsan,

Thank you very much! It has clicked in place now. Sorry, that was a daft question - I didn’t realise that the labels were stored separately as an nx1 matrix in a different attribute and that the embedding would not rearrange the order of points.

Thanks again for your help! Take care, Tim
