fix(load): issue load path of dataset and virtualized=true error on csv

[ArslanSaleem]

Important

Fix dataset path validation and unsupported virtualization error handling, with minor refactoring and type hint correction.

• Behavior:
  • In pandasai/__init__.py, load() now raises ValueError if dataset_path is not in 'organization/dataset' format.
  • In loader.py, load() raises ValueError for unsupported virtualization of CSV and Parquet files.
• Refactoring:
  • Introduced _get_abs_dataset_path() in loader.py to centralize dataset path construction.
  • Replaced direct path construction with _get_abs_dataset_path() in _load_schema(), _get_cache_file_path(), and _load_from_source().
  • Added _get_table_name() in query_builder.py for table name retrieval.
• Type Hints:
  • Changed min_version type hint in import_dependency() in environment.py from str | None to Union[str, None].

1. pandasai/chat/code_execution/environment.py:95

• Draft comment:
  In Python 3.10+, str | None is valid syntax and more concise than Union[str, None]. Consider using it if compatibility with older versions is not a concern.
• Reason this comment was not posted:
  Confidence changes required: 33%
  The change from str | None to Union[str, None] is unnecessary in Python 3.10+ where the former is valid syntax. However, it might be for compatibility with older versions.

2. pandasai/data_loader/query_builder.py:24

• Draft comment:
  The _get_table_name method is defined twice, once here and once in loader.py. Consider refactoring to avoid redundancy.
• Reason this comment was not posted:
  Confidence changes required: 50%
  The _get_table_name method is defined twice, once in query_builder.py and once in loader.py. This is redundant and can lead to maintenance issues.

3. pandasai/__init__.py:89

• Draft comment:
  Consider stripping leading and trailing slashes from dataset_path to avoid path format issues.
• Reason this comment was not posted:
  Confidence changes required: 50%
  The load function in __init__.py checks for a specific path format but does not handle cases where the path might have leading or trailing slashes, which could cause issues.

4. pandasai/data_loader/loader.py:54

• Draft comment:
  The error message should be more specific and grammatically correct.

                    raise ValueError("Virtualization is not supported for CSV and Parquet file types.")

• Reason this comment was not posted:
  Comment looked like it was already resolved.

5. pandasai/data_loader/query_builder.py:28

• Draft comment:
  The error message should be more specific and grammatically correct.

            raise ValueError("Table name is not found in the schema.")

• Reason this comment was not posted:
  Decided after close inspection that this draft comment was likely wrong and/or not actionable:
  The original error message is already clear and grammatically correct. The suggested change is more formal but does not significantly improve clarity or correctness. The comment does not point out a clear issue that requires a change.
  I might be underestimating the importance of consistency in error message phrasing across the codebase, which could be a reason to adopt the suggested change.
  While consistency is important, the current message is not incorrect or unclear, and the suggestion does not provide a substantial improvement.
  The comment does not highlight a necessary change, as the original error message is already clear and correct. The comment should be deleted.
