About ML Logs

The ML Logs page, accessible from the ML Logs menu after selecting a project, is a consolidated view of all events related to the project.



These events fall into the following categories:

  • ML Package validation events
  • Dataset events
  • Pipeline events
  • ML Skill deployment events
  • ML Skill predictions events

ML Package Validation Events

When a model is uploaded, if the model is not marked as Trainable, UiPath AI Center™ validates the uploaded .zip file against the following requirements:
  • A non-empty root folder with the same name as the zip file exists.
  • A requirements.txt file exists.
  • A file named main.py which implements a class Main exists. The class is further validated to implement an __init__ and a predict function.
If the model is marked as Trainable, AI Center validates the uploaded .zip file against the following requirements:
  • A non-empty root folder with the same name as the zip file exists.
  • A requirements.txt file exists.
  • A file named main.py which implements a class Main exists. The class is further validated to implement an __init__ and a predict function.
  • A file named train.py which implements a class Main. The class is further validated to implement an __init__ function as well as train, evaluate, and save functions.
  • Note an optional train_requirements.txt file can be added; if not included, the validation still passes.

ML logs for this category illustrate validation start and finish times, and the actual validation errors, if any.

Dataset Events

When a dataset is created, updated, or deleted, it is displayed in the ML Logs page.

Pipeline Events

When a pipeline starts or fails, it is displayed here.

ML Skill Deployment Events

When a skill is created, AI Center deploys it. This entails installing dependencies, running a number of security checks and optimizations, setting up the network within the namespace of the tenant, creating a container with a certain number of replicas from the corresponding package, and finally checking the health of the skill.

ML logs for this category illustrate deployment start and finish times, and the actual deployment errors, if any.

ML Skill Predictions Events

When a live skill is serving, if there is a prediction failure - an exception thrown by the Python code, the corresponding exception is under this component.
