  4. ' HTTP Error 403: Forbidden'

    I keep on getting ' HTTP Error 403: Forbidden' every time i try to import a csv file into JupyterLab. This only occurred recently, I've had no problems before. This is true for chrome and explorer.

  6. Missing all Lab Files

    I am not able to find files (Jupyter Notebooks) under lab section on Jupyter Lab.

    It says:
    Cannot openCould not find path: /labs/DV0101EN/DV0101EN-1-1-1-Introduction-to-Matplotlib-and-Line-Plots-py-v2.0.ipynb

    Also all the previous files are missing from labs directory.
    How can I practice, if I do not get the jupyter files with exercises in it. There were other directories too, from other courses.
    Please restore everything for me.

  15. Install Ta-lib

    I follow the knowledge base suggestion to install Ta-lib: !conda install -c quantopian ta-lib --yes

    However, I encountered the following error messages.

    Solving environment: failed

    UnsatisfiableError: The following specifications were found to be in conflict:
    - scikit-learn==0.20.1
    - ta-lib
    - tensorflow==1.8.0
    Use "conda info <package>" to see the dependencies for each package.

    Can you tell me how to solve this problem?

    Thank you
