**Instructions:**
|
| 355 |
-
|
| 356 |
-
1. Please clone this space, then modify the code to define your agent's logic, the tools, the necessary packages, etc ...
|
| 357 |
-
2. Log in to your Hugging Face account using the button below. This uses your HF username for submission.
|
| 358 |
-
3. Click 'Run Evaluation & Submit All Answers' to fetch questions, run your agent, submit answers, and see the score.
|
| 359 |
-
|
| 360 |
-
---
|
| 361 |
-
**Disclaimers:**
|
| 362 |
-
Once clicking on the "submit button, it can take quite some time ( this is the time for the agent to go through all the questions).
|
| 363 |
-
This space provides a basic setup and is intentionally sub-optimal to encourage you to develop your own, more robust solution. For instance for the delay process of the submit button, a solution could be to cache the answers and submit in a seperate action or even to answer the questions in async.
