The valohai.yaml configuration file is the blueprint for your project. It contains information about how to run steps and pipelines and how to create deployment endpoints.
It is possible to automate writing the yaml file with valohai-utils but in some cases you might need to do that by hand. To make sure the indentation is correct and all the steps contain the required properties, it is recommended to run the command
vh lintin the directory where you have the valohai.yaml to check for any syntax errors.
One of the common reasons for errors when trying to fetch a Git repository to Valohai are syntax errors in
valohai.yaml.
Can you spot what is wrong in the example below?
---
- step:
name: preprocess-dataset
command:
- pip install numpy valohai-utils
- python ./preprocess_dataset.py
inputs:
- name: dataset
default: https://valohaidemo.blob.core.windows.net/mnist/mnist.npzRunning the vh lint command reveals that required property image is missing from the step!
