Error when running UMAP about parc

[ShobiStassen]

Hi, i have the following suggestion until i get around to doing a proper fix.
I just installed and ran PARC with the hybrid umap construction on a clean environment and get it to work by ensuring that 1) numba is version 0.49.1 and 2) umap-learn is 0.4.3

import parc
import matplotlib.pyplot as plt

from sklearn import datasets

iris = datasets.load_iris()
X = iris.data
y = iris.target

p1 = parc.PARC(X, true_label=y, too_big_factor=0.3, resolution_parameter=1, keep_all_local_dist=True)  
p1.run_PARC()
print(type(p1.labels), p1.stats_df)

graph = p1.knngraph_full()
X_umap = p1.run_umap_hnsw(X, graph)
plt.scatter(X_umap[:, 0], X_umap[:, 1], c=p1.labels)
plt.show()
plt.scatter(X_umap[:, 0], X_umap[:, 1], c=y)
plt.show()

These are the commands in a new venv :
conda create --ParcEnv2021 python=3.7
conda install pip
pip install matplotlib
pip install umap-learn==0.4.3 
pip install numba==0.49.1
pip install leidenalg #0.7.0 is faster so you could consider using 0.7.0 version for large data
pip install hnswlib
pip install python-igraph
pip install parc

Thank you, @ShobiStassen! All is well now.

I received an compilation error when for "pip install leidanalg==0.7.0" but "pip install leidanalg" worked fine. It gave me 0.8.4. I did see your inquiry here: vtraag/leidenalg#35

It seems they fixed the slow down issue??
