Fetch failed executions

Using the Valohai APIs is rather straightforward, you’ll need to create an API token to authenticate your requests and then write your code to send & receive requests.

• Go to your profile setting and create an authentication token
  • In our sample we’ll paste this directly to the file but you should consider saving this token in a configuration file or database for secure storage.
• Consider creating a custom virtual environment for Python before continuing.
  • python3 -m virtualenv .venv
  • source .venv/bin/activate
• You’ll need the ID of a single project to fetch its executions. You can get it from the projects’ setting page or query for it using the Valohai APIs results.
• Create a new file fetchExecutions.py

import requests
import json
import os

# Authenticate yourself with the token.
# Remember to follow your organization's security standards when handling the token. 
auth_token = os.environ['VH_API_TOKEN']
headers = {'Authorization': 'Token %s' % auth_token}

# Send a request (with the authentication headers) to fetch all executions in a project
# You can get the project ID for example
resp = requests.get('https://app.valohai.com/api/v0/executions/?project={project_id}', headers=headers)

# To fetch all failed executions you could run
# https://app.valohai.com/api/v0/executions/?project={project_id}&status=error

resp.raise_for_status()

# Print the response you've received back
print('# API Response:\n')
print(json.dumps(resp.json(), indent=4))

• Save and run python fetchExecutions.py and you’ll see a list of executions with their details.
