Update from 4.0 to 4.4 broke everything #134

ruslankotl commented 3 days ago

I have had problems with getting new version to work. I have installed a fresh version of REINVENT into a new folder, and my previous REINVENT 4 runs cannot be started with the old config files. One of the errors I observed was

ModuleNotFoundError: No module named 'reinvent.models.meta_data'

In addition, attempts to run a molecular optimisation using a pubchem mol2mol prior led to its tokeniser throwing an exception:

  File "/home/rk582/miniconda3/envs/reinvent4/lib/python3.10/site-packages/reinvent/models/mol2mol/dataset/dataset.py", line 25, in __init__
    enc = self._vocabulary.encode(tokenized)
AttributeError: 'dict' object has no attribute 'encode'

This is a very disappointing behaviour and I was wondering if there was a way to fix it.

Hi,

many thanks for your interest in REINVENT and welcome to the community!

I am sorry to hear that you are having difficulties installing the software. However, I would need considerably more information and what went wrong (full output of stack traces) and how you actually have installed REINVENT. I have just done a fresh install of 4.4.22 myself and cannot reproduce what you report.

Many thanks, Hannes.

Hi Hannes,

Deleting the folder, cleaning conda cache, and reinstalling did the trick, thanks!

Can you let me know what you did before? This would be helpful in avoiding the same problem for others. I suspect you had some leftover files in the directory.

There were quite a few things going on:

  1. I had custom components specified
  2. To distribute those within the group, I forked the 4.0 repository and added the components directly into reinvent_plugins/components
  3. As a result, updating to 4.4 led to several merge conflicts
  4. I also kept some useful scripts for automated config generation in the REINVENT folder, but I suspect adding them to .gitignore will solve the problem later on.

Thanks a lot for finally adding the PubChem Mol2Mol prior

Ok, I would keep the components separately. That's the whole idea of the plugin mechanism.
