    I had a feeling boto3 or its dependencies were causing this issue, and seemed to be right.
    I reinstalled Pythonista3 and imported flask without issues. Then I installed ptinstaller and stash and could still import flask (as expected). Then I installed boto3 (and deps) via pip/stash.
    Restarted pythonista and tried to import flask. Then I received this error again!
    Now I just installed flask via pip and this seems to work. I can now import flask and boto3.

    Thank you for your reply.
    I see in stash that flask was not installed using pip... I could install it with pip but I'm afraid for weird side effects..

    I suspect it must be something I installed which are causing this issues. I did install a few scripts using ptinstaller. I uninstalled them but still same error. I did install some packages using pip, like boto3. I'll check what others I installed using pip.

    This is the complete list:
    ywangd/pkg_resources (master) - Copied from setuptools so it can be downloaded separately without the whole lot
    aws (0.2.5) - Utility to manage your Amazon Web Services and run Fabric against filtered set of EC2 instances.
    boto (2.43.0) - Amazon Web Services Library
    Fabric (1.9.2) - Fabric is a simple, Pythonic tool for remote execution and deployment.
    PrettyTable (7) - A simple Python library for easily displaying tabular data in a visually appealing ASCII table format.
    boto3 (1.4.1) - The AWS SDK for Python
    botocore (1.4.66) - Low-level, data-driven core of boto 3.
    jmespath (0.9.0) - JSON Matching Expressions
    python-dateutil (2.5.3) - Extensions to the standard Python datetime module
    docutils (0.12) - Docutils -- Python Documentation Utilities
    s3transfer (0.1.9) - An Amazon S3 Transfer Manager
    futures (3.0.5) - Backport of the concurrent.futures package from Python 3.2
    pyte (0.4.10) - Simple VTXXX-compatible terminal emulator.

    When I import flask I get the error below. I had this before and resolved it by reinstalling pythonista. After reinstalling I can import flask without issues (I am not really using it yet in my scripts but plan to do so soon), but later it fails again.
    Any idea what could be wrong?
