Artifacts with long name are not shown correctly

[Chen-Cai-OSU]

Hello,

When I look into some visualizations for different experiments, I found that if artifacts have very long names, they can not be shown correctly. For example, umap_{'neu_idx': 0}{'n_neighbors': 10, 'min_dist': 0.1, 'n_components': 2, 'metric': 'euclidean'}.jpg can not be shown but tsne{'neu_idx': 2}_{'metric': 'euclidean'}.jpg can be shown correctly.
