fix(load): update error message in case of dataset not found locally and missing api keys

[ArslanSaleem]

Important

Update error message and add print statement in load() for missing local dataset and API key, with new test added.

• Behavior:
  • Update error message in load() in pandasai/__init__.py when dataset not found locally and no API key is provided.
  • Add print statement in load() to indicate if dataset was loaded locally or fetched from remote server.
• Tests:
  • Add test_load_missing_not_found_locally_and_no_remote_key in test_pandasai_init.py to verify updated error message.

More details

• Looked at 97 lines of code in 2 files
• Skipped 0 files when reviewing.
• Skipped posting 5 drafted comments based on config settings.

1. pandasai/__init__.py:222

• Draft comment:
  Consider rewording the error message. For example: "The dataset '{dataset_path}' was not found in your local datasets directory, and no API key was provided. Please set a valid API key to fetch the dataset from the remote server." This improves clarity and conciseness.
• Reason this comment was not posted:
  Marked as duplicate.

2. pandasai/__init__.py:243

• Draft comment:
  Avoid using print() in library code. Consider using a proper logging mechanism instead.
• Reason this comment was not posted:
  Marked as duplicate.

3. tests/unit_tests/test_pandasai_init.py:143

• Draft comment:
  Ensure that tests are updated to reflect the changes in exception messages and types. The new detailed message should be verified in tests consistently.
• Reason this comment was not posted:
  Marked as duplicate.

4. tests/unit_tests/test_pandasai_init.py:160

• Draft comment:
  Test 'test_load_missing_api_url' now expects DatasetNotFound. Ensure this test clearly distinguishes the scenario of a missing remote dataset (HTTP 404) versus missing credentials, as these branches raise different exceptions.
• Reason this comment was not posted:
  Comment did not seem useful.

5. tests/unit_tests/test_pandasai_init.py:220

• Draft comment:
  Update the expected error message in 'test_load_without_api_credentials' to match the new, more descriptive error message. Also, consider phrasing improvements like using 'permissions' instead of 'permits'.
• Reason this comment was not posted:
  Comment was not on a location in the diff, so it can't be submitted as a review comment.
