Production mode
When running a Taipy Core application in --production
mode, Taipy can access all entities
attached to the current version or another production version. It corresponds to the case where
the application is stable and running in a production environment.
In the following, we consider the basic Taipy Core application main.py
for all our examples:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 |

Convert an experiment in production¶
To convert an experiment version to a production, you can run the Taipy application
on your command line interface with --production VERSION
option providing the version name.
$ python main.py -l

In the example above, Taipy converted the version 1.0 to a production version before running it.
Without explicitly providing the version, the latest version of your application is used. Here is another example:
$ python main.py --experiment 2.0
[2023-01-25 13:05:17,712][Taipy][INFO] job JOB_my_print_algo_ac79138a-4c3a-4560-bbd4-f4975083bf83 is completed.

$ python main.py --production

As you can see, we first created an experiment version named 2.0. One scenario is attached to it. When listing the existing versions, we can see that 2.0 is the latest version used. So when running the Taipy application in production mode without providing the version, the latest is used and converted to production before running. Note that once the version is converted to production, the application accesses all production entities, including from older production versions.
Remove a production version¶
To remove a production version, you can run on your command line interface a Taipy
application with the --delete-production-version VERSION
option providing the version
name.
$ python main.py --delete-production-version 2.0
Successfully delete version 2.0 from production version list.
$ python main.py -l
Version number Mode Creation date
2.0 Experiment (latest) 2023-01-25 13:06:00
1.0 Production 2023-01-25 13:00:05
325d0618-6f9e-459b-9597-48fa93a57a23 Experiment 2023-01-25 12:20:56
26e56e84-9e7e-4a26-93f6-443d9aa541d9 Development 2023-01-25 12:20:33
After running the commands above, version 2.0 is an experiment version again. It is no longer a production version.
