AttributeError: 'MolDraw2DSVG' object has no attribute 'SetDrawOptions'

import pandas as pd
import mols2grid

smiles = ["CCO", "c1ccccc1", "N", "CO", "O=S(=O)(-O)(-O)", "CCC", "CCC=O"]
df = pd.DataFrame({"smi": smiles,
                   "id": range(1, len(smiles) + 1)})
mg = mols2grid.MolGrid(df, smiles_col="smi", size=(110, 90))
mg.display(subset=["id", "img"], n_cols=7)

I was trying to visualize a list of SMILES, as shown in your colab. But I got the following error message.

could you please take a look maybe? Thanks!

Hi, thank you very much! After updating RDKit to 2020.09.1.0, the script works well for me (sorry for the sluggish feedback, I don’t know why but my desktop takes a very long time to uninstall old RDKit vai conda:))

I’ve updated the installation instructions on the readme file with the correct rdkit version.
If you install mols2grid from conda the correct rdkit version will now automatically be installed, which closes this issue.
