            Python/Docker ImportError: cannot import name 'json' from itsdangerous
            Asked 2022-Mar-31 at 12:49

            I am trying to get a Flask and Docker application to work but when I try and run it using my docker-compose up command in my Visual Studio terminal, it gives me an ImportError called ImportError: cannot import name 'json' from itsdangerous. I have tried to look for possible solutions to this problem but as of right now there are not many on here or anywhere else. The only two solutions I could find are to change the current installation of MarkupSafe and itsdangerous to a higher version: and another one on GitHub that tells me to essentially change the MarkUpSafe and itsdangerous installation again, I have also tried to make a virtual environment named veganetworkscriptenv to install the packages but that has also failed as well. I am currently using Flask 2.0.0 and Docker 5.0.0 and the error occurs on line eight in

            Here is the full ImportError that I get when I try and run the program:

            I was facing the same issue while running docker containers with flask.

            I downgraded Flask to 1.1.4 and markupsafe to 2.0.1 which solved my issue.

            Poetry | AttributeError 'Link' object has no attribute 'name'
            Asked 2022-Mar-23 at 10:22

            I want to install packages from poetry.lock file; using poetry install.

            However, the majority of packages throw the exact same error, indicating a shared fundamental problem.

            What is causing this? What is the standard fix?


            • Windows 10,
            • Visual Studio Code,
            • Python 3.8.10 & Poetry 1.1.11,
            • Ubuntu Bash.

            This looks to be an active issue relating to poetry. See here - Issue #4085. Some suggest a workaround by downgrading poetry-core down to 1.0.4.

            There is an active PR to fix the issue.



            ImportError: cannot import name 'tasks_v2' from '' (unknown location) in Python fastapi
            Asked 2022-Feb-09 at 17:35

            I'm trying to incorporate google-cloud-tasks Python client within my fastapi app. But it's giving me an import error like this:



            Answered 2022-Feb-09 at 17:35

            After doing some more research online I realized that installation of some packages is missed due to some existing packages. This issue helped me realize I need to reorder the position of google-cloud-tasks in my requirements.txt. So what I did was pretty simple, created a new virtualenv installed google-cloud-tasks as my first package and then installed everything else and finally the problem is solved.

            Long story short the issue is the order in which packages are installed and that's why some packages are getting missed.

            Your issue is, I think, with your requirements file. In that you include bson as a dependency, which is also included in the pymongo library. See this question. Removing it seems to solve the issue:



            Successful build of Heroku Python App but execution is unsuccessful and open app throws error
            Asked 2022-Jan-03 at 16:25

            I recently successfully deployed a Heroku app(view log below for details), but when I try to access my app through a browser, it returns with An error occurred in the application and your page could not be served. If you are the application owner, check your logs for details. You can do this from the Heroku CLI with the command heroku logs --tail. Furthermore, my app was for a Discord.Py bot, and the bot was not online like it should be.




            Answered 2022-Jan-03 at 16:25

            Your application is a worker (Procfile declares types -> worker) so it does respond to HTTP requests.

            Change to web and make sure you bind the PORT provided by Heroku.

            BTW BOTs can run as workers (without dealing with incoming requests) if they poll the server for messages/updates. This is a viable option too (keep it as worker) but ensure the BOT logs what it does at startup.



            Python cfn_tools module won't load in AWS CodeBuild running in AWS CodePipeline
            Asked 2021-Dec-20 at 19:11

            I have been getting the following error in my CodeBuild execution: ModuleNotFoundError: No module named 'cfn_tools'

            Interesting note, the first time I ran this through CodeBuild with this module I had no issues. It only started happening after I made my next gitHub push that kicked off my pipeline that I saw this. The files that are related to this didn't change, and the modifications in that next push were to an unrelated section of the repo.

            I have since tried to do:

            • pip install cfn-tools & pip3 install cfn-tools which mentioned that the module was already installed. These were added to the BuildSpec section. No success - still got the error
            • I've added a requirements.txt file with no success still got the error. I created this file using pip freeze also within the BuildSpec. The module shows up, but still get the error.
            • Originally used runtime version 3.7 of python and then tried with 3.9 which still didn't work.

            python runtime 3.9 Any assistance would be appreciated.

            UPDATE: To add more information I download a .tar.gz file from S3 that contains the python scripts I need for running in this build. I extract the .tar.gz then I run the script that is having the error. Here is the output for when I install cfn-tools and do a pip freeze You will see below that cfn-tools loads and is part of the output of pip freeze but yet when I run my script it give me the above error.



            Answered 2021-Dec-20 at 19:11

            The module I was trying to install wasn't the one that was being used.

            The module that needed to be installed was cfn_flip it has the cfn_tools module that the code was trying to use. The CodeBuild didn't have it installed, so how it worked on the first run is still a mystery.

            Dash/Plotly - long_callback fails with celery/redis backend
            Asked 2021-Oct-21 at 04:03

            I’ve been developing a dash app that uses a long_callback, and for development I’ve been using a diskcache backend for my long_callback_manager, as recommended by the guide I found here:

            When I tried running my app using gunicorn, it failed to start because of something apparently wrong with diskcache. As such, I decided to switch to a celery/redis backend since that’s recommended for production anyway.

            I got a redis server running (responds properly to redis-cli ping with PONG), and then started the app again. This time it started up fine, and all of the normal callbacks work, but the long_callback does not work.


            • The page more or less hangs, with the page title flashing between the normal title and the Updating... title, indicating that the app thinks it’s “waiting” for a response/update from the long_callback.
            • The values set by the running argument of the long_callback are set to their starting value, indicating that the app recognizes that the long_callback ought to run.
            • By placing a print statement as the first line within the long_callback function and seeing that it does not print, I’ve determined that the function never starts.
            • The failure happens both with gunicorn and without gunicorn.

            These details all point to the problem being the celery/redis backend. No errors are shown, neither on the client/browser nor on the server’s stdout/sterr.

            How do I get a celery/redis backend working?

            UPDATE: After realizing that the __name__ variable is being used and that its value changes depending on the file from which it is referenced, I've also tried moving the code which creates celery_app and LONG_CALLBACK_MANAGER into, to no avail. The exact same thing happens.

            Code ...


            Answered 2021-Oct-21 at 04:03

            Re-posting the solution from the plotly community forum:


            In order for the long callback to work, I needed to start 3 separate processes that work in conjunction:

            1. the Redis server: redis-server
            2. the Celery app: celery -A app.celery worker --loglevel=INFO
            3. the Dash app: python

            The commands listed above are the simplest version. The full commands used are given further down with appropriate modifications.


            I moved the declaration of the celery app from src/website/ to src/ for easier external access:
