Random seed
Closed this issue · 5 comments
Hi, I tried to run the program with a fixed seed to ensure my analysis was fully reproducible. I expected that the numeric value I set with --seed
would be the same as the value listed in the console output after Seed:
. However, these values do not match. Should these values match? I am running root digger in a container which was built using the Dockerfile in this repo.
They should, and in fact they do on my end. HOWEVER: rootdigger always reloads from a checkpoint if possible, and the seed is stored in the checkpoint. Please make sure that you aren't loading from a checkpoint. There should be a line like
[0.00] [Warning] Loading options from the checkpoint file. Some cli options are ignored. If the program is not working, try deleting the checkpoint file
if you are.
Thanks @computations, where can I find this checkpoint file? Also, I noticed when running the container with --no-home
option (do not mount the home dir) it didn't find the checkpoint file: There was an error during processing: Failed to open the checkpoint file
. I am wondering, is it possible to read/write this file from/to the working directory?
The checkpoint is name <PREFIX>.ckp
, and the default prefix is the name of the tree file.

I'm a little unclear what you mean here, however I am going to try and answer it. The checkpoint file contains all the results (along with some other details), and is written to continuously throughout the run. So, the location of the checkpoint file requires both read and write permissions.
Failed to open the checkpoint file
only came up because of some silly container mistake on my end. Thanks @computations for your clarification around the checkpoint file. All clear, --seed
works as intended.
No problem, happy to help!
