How does Weights json file work? #127

Open jdini76 opened 2 years ago

jdini76 commented 2 years ago

Could someone provide an example of how the weights json file is supposed to be formatted and how it works? There are no examples in the project or any documentation on it.

I figured it out. This response is for others wondering. The weights json file is automatically created/updated after a 100% successful run. So it might be best to run through your scripts with a single thread to generate an initial weights json file. Then, in corresponding executions it will read the weights file to properly distribute the specs across the threads.

After a couple of test here, I found out that, for us at least with 3 threads, the file generated after a run with all 3 threads is better than a file generated with only 1 thread.
