# Maintaining back-compatibility with come legacy versions
|
||
|
|
|
||
|
|
The aim of this section is set some baselines and workflows/guidelines for maintaining back compatibility with some legacies version of PL
|
||
|
|
|
||
|
|
At this moment we focus on ability running old checkpoints, so the flow here is to create a checkpoint with every release and store it in our public AWS storage and so each CI testing will pull this archive and test loading and resuming training with this model.
|
||
|
|
|
||
|
|
If you want to pull all saved version-checkpoints for local testing/development, call
|
||
|
|
```bash
|
||
|
|
wget https://pl-public-data.s3.amazonaws.com/legacy/checkpoints.zip
|
||
|
|
unzip -o checkpoints.zip
|
||
|
|
```
|
||
|
|
|
||
|
|
To back populate collection with past version you can use following bash:
|
||
|
|
```bash
|
||
|
|
bash generate_checkpoints.sh 1.0.2 1.0.3 1.0.4
|
||
|
|
zip -r checkpoints.zip checkpoints/
|
||
|
|
```
