Persistent ImportError: 'get_prices' missing from quantrocket.history (v2.11.0, after full container/image recreation)

Technical Help
#1

Dear QuantRocket Support,

I am experiencing a persistent ImportError when attempting to use get_prices from quantrocket.history in my JupyterLab environment. This occurs despite running QuantRocket version 2.11.0.

Problem Description:
When I run from quantrocket.history import get_prices, list_sids in a Jupyter Notebook cell, I receive the following error:

System Information:

  • QuantRocket Version: 2.11.0
  • Deployment Type: Self-hosted (on Windows, using Docker Desktop)
  • Python Version in Jupyter: 3.11

Troubleshooting Steps Taken (with results):

  1. Initial query attempt: Received the ImportError.
  2. Jupyter Kernel Restart (Kernel -> Restart & Clear Output): Did not resolve the error.
  3. Attempted !pip install --upgrade quantrocket in Jupyter Notebook: Failed with ERROR: Could not find a version that satisfies the requirement quantrocket (from versions: none) and ERROR: No matching distribution found for quantrocket. This indicated pip could not find the package.
  4. Confirmed Docker not available in Jupyter terminal: docker info resulted in zsh: command not found: docker.
  5. Attempted quantrocket service stop/start jupyter in Jupyter terminal: Failed with invalid choice: 'service'.
  6. Accessed host machine's terminal (Windows Command Prompt/PowerShell): Successfully ran docker commands.
  7. Restarted Jupyter container (docker restart quantrocket-jupyter-1): Container restarted, but the ImportError persisted in JupyterLab.
  8. Direct inspection of quantrocket.history module in Jupyter Notebook (dir(quantrocket.history)):
    • Output: ['FilepathOrBuffer', 'Literal', 'NoHistoricalData', 'TMP_DIR', 'Union', '__all__', '__builtins__', '__cached__', '__doc__', '__file__', '__loader__', '__name__', '__package__', '__spec__', '_cli_cancel_collections', '_cli_collect_history', '_cli_create_custom_db', '_cli_create_edi_db', '_cli_create_ibkr_db', '_cli_create_sharadar_db', '_cli_create_usstock_db', '_cli_download_history_file', '_cli_drop_db', '_cli_get_db_config', '_cli_get_history_queue', '_cli_list_databases', '_cli_list_sids', '_cli_wait_for_collections', 'cancel_collections', 'collect_history', 'create_custom_db', 'create_edi_db', 'create_ibkr_db', 'create_sharadar_db', 'create_usstock_db', 'dict_strs_to_dict', 'dict_to_dict_strs', 'download_history_file', 'drop_db', 'get_db_config', 'get_history_queue', 'houston', 'json_to_cli', 'list_databases', 'list_sids', 'os', 'requests', 'sys', 'wait_for_collections', 'write_response_to_filepath_or_buffer']
    • Finding: get_prices is explicitly NOT in this list, confirming it's missing from the loaded module. list_sids is present.
  9. Direct inspection of history.py file content in Jupyter Notebook:
    • Ran code to read /opt/conda/lib/python3.11/site-packages/quantrocket/history.py.
    • Finding: The output explicitly stated 'def get_prices' NOT found in the file. This confirms the file being loaded literally lacks the function.
  10. Aggressive Docker image purge and container recreation:
    • docker stop quantrocket-jupyter-1
    • docker rm quantrocket-jupyter-1
    • docker rmi quantrocket/jupyter:2.11.0 (successfully deleted the image)
    • docker compose up -d jupyter (successfully pulled a fresh image and started container)
    • Result: Despite this, the ImportError for get_prices still persists after refreshing JupyterLab and rerunning the code.

Expected Behavior:
Based on QuantRocket v2.11.0 documentation, get_prices should be available in quantrocket.history and allow querying of loaded data.

Request:
Could you please assist in diagnosing this persistent environment issue? It seems the Jupyter container's Python environment is not correctly loading the quantrocket client library despite thorough recreation efforts.

Thank you for your time.

get_prices is in quantrocket, not quantrocket.history:

from quantrocket.history import list_sids
from quantrocket import get_prices
