Parameters
x = torch.multinomial(prob).view(-1) This function procedure is wrong. How do I fill in this parameter? What parameters should I fill in num_samples? Thanks
Hi, please make sure that you are running pytorch 0.1.12. This error only occurs in newer version of pytorch as they changed the api. Cheers, Thomas

Dear Thomas,thanks for your letter: I changed it x = torch.multinomial(prob,1).view(-1) ,The program can run normally. But I made new mistakes again. Results after program running is [10:19:53] SMILES Parse Error: syntax error for input: '()GO(O' [10:19:53] SMILES Parse Error: syntax error for input: '2-212121O' [10:19:53] non-ring atom 0 marked aromatic [10:19:53] SMILES Parse Error: syntax error for input: 'GO2' [10:19:53] SMILES Parse Error: syntax error for input: '(GO' [10:19:53] SMILES Parse Error: extra close parentheses for input: 'O11)-c-c-GOc)((-2c)GO1' [10:19:53] SMILES Parse Error: syntax error for input: 'GOcO-(cGO-2((c--1GO-' I would like to ask why this happens. thanks!

These errors are generated by rdkit when the model generates non valid SMILES. The generated SMILES (e.g 2-212121O ) are completely wrong and the included Prior doesn’t usual generate these kind of SMILES. I’m not sure where you input a single SMILES to get this result. main.py doesn’t take single SMILES as input. Please make sure that you use the old pytorch version and you are able to run the main.py command from the readme.

It seems that you have a completely biased prior which only produces a few different smiles. This error occurs when you have less then 10 different smiles in one batch. By default we generate 128 smiles and simply print the first unique 10 smiles during the training. Please dramatically increase your training set (or simply use the included chembl dataset) or adjust the code if you really just want to create less than 10 sequences...

Cheers, Thomas Dear Thomas,I am sorry to bother you agin.I would like to ask you: when we generate a new molecule, we want to test its molecular weight, ClogP. Can you provide the source code? Thank you very much indeed.
