Flask server cannot start due to the lack of libgcc

I have created flask server for my app, which I want to run on raspbian, on raspberry pi. When trying to start with flask run I've got info that libgcc_s.so.1 must be installed for pthread_cancel to work Aborted.
It looks like server has been started, but just after that it has been immediately stopped.
Tryed already to install libgcc-8-dev via apt-get install but no success.
Also found that library can be downloaded from here: https://packages.debian.org/cgi-bin/search_contents.pl?word=libgcc_s.so.1&searchmode=searchfiles&case=insensitive&version=stable&arch=i386
but I have no idea which one should I pick and how to install it properly (where to place it and how to link it)?

If you using something like openCV, then try to find out its headless version.
For me that problem was coming due to openCV. Then I install its headless version and it works fine.
Example:- sudo pip3 install opencv-python-headless

How can I make this script run

I found this script (tutorial) on GitHub (https://github.com/amyoshino/Dash_Tutorial_Series/blob/master/ex4.py) and I am trying to run in my local machine.
Unfortunately I am having and Error
I would really appreciate if anyone can help me to run this script.
Perhaps this is something easy but I am new in coding.
Thank you!

You probably just need to pip install the dash-core-components library!
Take a look at the Dash Installation documentation. It currently recommends running these commands:
pip install dash==0.38.0 # The core dash backend
pip install dash-html-components==0.13.5 # HTML components
pip install dash-core-components==0.43.1 # Supercharged components
pip install dash-table==3.5.0 # Interactive DataTable component (new!)
pip install dash-daq==0.1.0 # DAQ components (newly open-sourced!)
For more info on using pip to install Python packages, see: Installing Packages.
If you have run those commands, and Flask still throws that error, you may be having a path/environment issue, and should provide more info in your question about your Python setup.
Also, just to give you a sense of how to interpret this error message:
It's often easiest to start at the bottom and work your way up.
Here, the bottommost message is a FileNotFound error.
The program is looking for the file in your Python37/lib/site-packages folder. That tells you it's looking for a Python package. That is the directory to which Python packages get installed when you use a tool like pip.

Using Flask and Jython under Windows 7

Hello everyone,
So I have been trying to use Jython to connect to an API Rest and retrieve some information. Now I want to use the Flask Framework with it. I have been trying to install the Flask with Jython but it does not seem to work at all. I am working on a Windows 7 machine and the problem for me is also that I can not download directly from the internet. For all other framework I used python wheels and installed these with Jython which worked fine.
I already tried to following commands and got these errors:
First error that I got was that it could not find the 'init.py' file in the flask folder so I changed the path in the file to the total path. But it just continued to give me more errors.
jython -m pip install '*.whl
Screenshot of the command line ouput of the error
pip install '*.whl (same as above)
I am a little stuck here and I hope that someone has an idea on how to solve this problem.
Big thanks already!!

This appears to be a bug with Jython 2.7.0. See this error report in pip and this one in Jython.
The second of those indicates that it is fixed in the 2.7.1 release candidate.

Running django-admin.py startproject is giving me an error

I've just started looking into python and django.. Im pretty sure ive successfull installed both python and the django framework and i managed to add python and django-admin.py to my system path but now when i run the command django-admin.py startproject My_Test_Site, in the folder i want to create a new project directory in (just following the tutorials), i get the following error:
What am i doing wrong?

This is not a Django error. It appears it cannot find the Python module unicodedata which is part of the Python Standard Library (docs). I see that there is also a bug report about this issue (Python 2.7 on Windows, see here). On the other hand, some people there report that reinstalling their Python installation fixed the problem. You could give that a try.

notice the last line, it says import unicodedata, importError
im guessing you probably didnt install your django properly.
so reinstall it and check that django is in your "path", i believe django does this automatically when it installs but doesnt hurt to double check.
if reinstalling django still doesn't work, i suggest you uninstall python and django related stuff.
then install python, install pip, then use pip install django.

ImportError exception encountered while trying to use Fabric

I am using Ubuntu and virtualenv, and I am having this recurring problem, while attempting to use Fabric to create a deployment script. Fabric depends on paramiko, which depends on PyCrypto.
Each time I try to use Fabric, or PyCrypto directly, I get this error:
ImportError: cannot import name Random
I have tried reinstalling with pip install -U PyCrypto. I have also tried installing the python-crypto and python-crypto-dbg packages with Aptitude, to no avail. I still get the same error. Anyone have any ideas that might help me solve this problem? Thanks in advance!

It's possible that there's a file name collision in your the directory from which you're running Fabric. Do you have a file called Crypto.py in your project?
Can you get Crypto.Random to import from outside of your project directory? (but still using your virtualenv. Ipython is a big help here.)

I've had the same trouble in the past using Ubuntu. I no longer have a Ubuntu install available, but on my old 10.04 box, the file Random in the Crypto directory was missing. Make sure it exists, if it doesn't, that's the problem.
