Rogi score calculated but unable to generate 2D and 3D plots

[albertma1986]

Hi, I am trying to calculate the ROGI score of a latent space (128-dimension) with respect to their corresponding IC50 values and plot the landscape. I managed to obtain a ROGI value of 0.159 however it could not draw the 2D/3D plots when I use the functions in https://github.com/coleygroup/rogi-results/blob/main/landscapes_viz.ipynb
I have done the same on other datasets (same IC50 values but different latent spaces, the dimension is 512) and work fine
What is the possible reason behind? Would that be dimension of 128 being too small?

transvae_ri_euclidean = RoughnessIndex(Y=df_transvae_Y, X=df_transvae, metric='euclidean')
transvae_rogi_score = transvae_ri_euclidean.compute_index()
print(transvae_rogi_score)

df_transvae
