            Dash ImportError: cannot import name 'get_current_traceback' from 'werkzeug.debug.tbtools'
            Asked 2022-Mar-30 at 07:41

            I'm trying to run a simple dash app in a conda environment in Pycharm, however I'm running into the error in the title. Weirdly enough, I couldn't find a place on the internet which has a mention of this bug, except for here. The code is simple, as all I'm trying to run is a simple dashapp; code obtained the code from here. I have tried switching between python versions in conda (back and forth between python 3.9, 3.8 and 3.7) but the error seems to be persistent. I know I have also correctly installed all its dependencies as I'm not getting any import error. Would appreciate if anyone could help with this.

            Edit: Versions of Dash installed, as requested by @coralvanda :

            Basically, I just did a pip install of everything so all the versions of packages are the latest.

            While I am testing my API I recently started to get the error below.



            Answered 2022-Mar-29 at 13:29

            As of version 2.1.0, werkzeug has removed the as_tuple argument to Client. Since Flask wraps werkzeug and you're using a version that still passes this argument, it will fail. See the exact change on the GitHub PR here.

            You can take one of two paths to solve this:

            1. Upgrade flask

            2. Pin your werkzeug version

            Asked 2022-Mar-28 at 21:19

            any ideas why this error?

            my project was working fine, i copied it to an external drive and onto my laptop to work on the road, it worked fine. i copied back to my desktop and had a load of issues with invalid interpreters etc, so i made a new project and copied just the scripts in, made a new requirements.txt and installed all the packages, but when i run i get this error



            Answered 2022-Mar-28 at 21:19

            Werkzeug released v2.1.0 today, removing werkzeug.security.safe_str_cmp.

            You can probably resolve this issue by pinning Werkzeug~=2.0.0 in your requirements.txt file (or similar).

            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.


            • rm poetry.lock
            • poetry update
            • poetry install


            Answered 2022-Mar-23 at 10:22

            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.

            1. Disbled Wayland by uncommenting WaylandEnable=false in the /etc/gdm3/custom.conf

            AWS Elastic Beanstalk - Failing to install requirements.txt on deployment
            Asked 2022-Feb-05 at 22:37

            I have tried the similar problems' solutions on here but none seem to work. It seems that I get a memory error when installing tensorflow from requirements.txt. Does anyone know of a workaround? I believe that installing with --no-cache-dir would fix it but I can't figure out how to get EB to do that. Thank you.




            Answered 2022-Feb-05 at 22:37

            The error says MemoryError. You must upgrade your ec2 instance to something with more memory. tensorflow is very memory hungry application.

            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:

            Install werkzeug

            You can install using 'pip install werkzeug' or download it from GitHub, PyPI.
            You can use werkzeug like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
