runsnake fails in ubuntu with error in squaremap

When I start runsnake with
$ runsnake test.profile
the window opens, but with no graphics and no source code (only the list of calls, etc. is present). On the console, I see the following error message:
11:18:17: Debug: Adding duplicate image handler for 'PNG file'

font.SetPointSize(scale * font.GetPointSize())
TypeError: Font.SetPointSize(): argument 1 has unexpected type 'float'
I installed runsnake using
sudo apt-get install runsnake
The versions of the dependencies are, according to pip list:
RunSnakeRun 2.0.5
SquareMap 1.0.5
wxPython 4.0.7
My system is
PRETTY_NAME="Ubuntu 22.04.1 LTS"
NAME="Ubuntu"
VERSION_ID="22.04"
VERSION="22.04.1 LTS (Jammy Jellyfish)"

A quick hack is to change the code that you run by modifying the code:
$ sudo $EDITOR /usr/lib/python3/dist-packages/squaremap/squaremap.py
Go to line 267
Then replace the line with:
font.SetPointSize(int(scale * font.GetPointSize()))
or hardcode someting:
font.SetPointSize(18)

Mac OS 11.4 Big Sur - fixing python cryptography package in /System/Library/Frameworks/Python.framework/Versions/2.7

I bought a MacBook Pro 13 M1 (16 GB RAM, 1 TB SSD) and I'm trying to get it setup for work and part of that is using python 2 (yes I know it's end of life, I still need to use it till we finish porting to go). I have some python packages I'd like to remove from my system python2 (I'm sure I must've run sudo pip install on these at some point, which I know was stupid, but what is done is done) and now that I'm on Big Sur I can't remove these packages. I tried disabling SIP until I can get them removed (csrutil disable from recovery), but now I'm getting errors that I can't remove files from a read only filesystem

How do I remove these files from /System/Library if it's read only? Do I have to format my system and start from scratch now that mac os put these files in a read only filesystem or is there a way to remove them?
Edit:
So I have broken packages in /System/Library that are preventing fabric from running so I can't get our stuff up and running. The main one being the cryptography package. So I either need to fix these packages so fabric can run or remove them or something.
The other part that makes this such a pain is that I'm trying to run python 2 on an M1 Mac which means either using the built in python or using rosetta with an x86 python2 as I have found no method for installing arm python 2 on an M1 Mac (there isn't an installer from python.org or brew since python2 was end of life when the M1 Macs shipped).
Edit2:
Maybe these packages that I'm having issues with did ship with Mac OS as the package's folder's created timestamp is "Jan 1 01:00:00 2020" just like every other file & folder in that same folder. If so I guess I need to fix them somehow. When I try to run fab from the command line I get this error in the cryptography package:

Has anyone else had this problem or have a fix for it?

I was able to install python2 for Apple Silicon/M1 from nix and then I had to manually install pip which let me install cryptography & cffi (I had libffi installed from brew). Here are the steps I used, I'm not sure if they're all necessary, but it's what I did:
Install Nix
see https://nixos.org/manual/nix/stable/#sect-macos-installation for more details, but if you have a mac with a T2 chip or M1 this will still be encrypted
sh <(curl -L https://nixos.org/nix/install) --darwin-use-unencrypted-nix-store-volume --daemon
Install python2 from nix
nix-env -i python-2.7.18
verify that you're using this python in a new terminal session (you'll need to start a new shell to get the updated path)
run which python
if it doesn't return something like /Users/user/.nix-profile/bin/python you'll want to add ~/.nix-profile/bin to the front of your path, start a new shell, and run which python again
Install pip
See https://pip.pypa.io/en/stable/installing/#installing-with-get-pip-py for more details, but if you curl the get-pip.py in this url and run it with python 2 it'll tell you to instead download and use the get-pip.py from https://bootstrap.pypa.io/pip/2.7/get-pip.py
curl https://bootstrap.pypa.io/pip/2.7/get-pip.py -o get-pip.py
python ./get-pip.py
Use brew to install libiff and openssl#1.1
I had done this step previously and I'm not 100% sure it's necessary, but I believe it is
brew install libiff openssl#1.1
Add the following to your .bashrc, .zshrc, .profile, or wherever you set your environment variables:
export LDFLAGS="-L$(brew --prefix openssl#1.1)/lib"
export CFLAGS="-I$(brew --prefix openssl#1.1)/include"
use pip to install cryptography
pip install cryptography
After this I had a functional python with cryptography installed and I was then able to install fabric (via pip install fabric==1.14.1 since 1.14.1 is the version I need for this old project, use what you need)
Edit:
Thanks to #CharlesDuffy for all of his help and as he correctly mentions in the comments bellow, you could (and probably should) install all of the dependencies and cryptography from nix instead of using a combination of brew and nix. I had brew and the dependancies installed before I had Nix installed so I haven't tested it out, but it should work.

How to resolve error: Poetry was not installed with the recommended installer. Cannot update automatically

I installed poetry using on mac using: curl -sSL https://raw.githubusercontent.com/python-poetry/poetry/master/get-poetry.py | python - several months ago.
When I run poetry self update -v I see the following error:

This error has been there since installation. I never found a solution. If it helps, I have Poetry version 1.0.5 installed, and when I run which -a poetry I get /Library/Frameworks/Python.framework/Versions/3.8/bin/poetry

simply add POETRY_HOME to your global env will solve this problem
e.g. in linux, add this line to your .profile
export POETRY_HOME="$HOME/.poetry/bin"

How to Install python3.8 on debian 10?

i've installed debian 10.0.4 yesterday on my pc.
it had python version 3.7.3 installed on it , so i tried to update it to version 3.8.3 and now i have version 3.8.3 installed but when i try to install pip using the official get-pip.py it throws an exception . the details is :
Traceback (most recent call last):
File "<frozen zipimport>", line 520, in _get_decompress_func

During handling of the above exception, another exception occurred:

i must mention that the python (python2.7) and pip for python 2.7 is working , and i tried to reinstall python using source compilation and i got another error while installing it (zlib error)

Installing Python 3.8 on Debian 10
Building Python 3.8 on Debian is a relatively straightforward process and will only take a few minutes.
Start by installing the packages necessary to build Python source:
sudo apt update
sudo apt install build-essential zlib1g-dev libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libsqlite3-dev libreadline-dev libffi-dev curl libbz2-dev liblzma-dev
Download the latest release’s source code from the Python download page with wget or curl. At the time of writing this article, the latest release is 3.8.2:
curl -O https://www.python.org/ftp/python/3.8.2/Python-3.8.2.tar.xz
When the download is complete, extract the tarball:
tar -xf Python-3.8.2.tar.xz
Navigate to the Python source directory and run the configure script:
cd Python-3.8.2
./configure --enable-optimizations --enable-loadable-sqlite-extensions
The script performs a number of checks to make sure all of the dependencies on your system are present. The --enable-optimizations option will optimize the Python binary by running multiple tests, which will make the build process slower.
Run make to start the build process:
make -j 4
Modify the -j to correspond to the number of cores in your processor. You can find the number by typing nproc.
Once the build is done, install the Python binaries by running the following command as a user with sudo access:
sudo make altinstall
Do not use the standard make install as it will overwrite the default system python3 binary.
At this point, Python 3.8 is installed on your Debian system and ready to be used. You can verify it by typing:
python3.8 --version
Python 3.8.2

How can I resolve this? Help me pls.

You can download a corresponding whl file from Unofficial Windows Binaries for Python Extension Packages
For example, the latest version (as of Jan 13 2019) for your 64-bit Windows and Python3.7 version is PyICU‑2.2‑cp37‑cp37m‑win_amd64.whl
Then open the Windows Powershell console as Administrator, cd to the directory where you put the whl file and execute the following command:
python -m pip install .\PyICU‑2.2‑cp37‑cp37m‑win_amd64.whl
or (if you already have a previous PyICU version installed)
python -m pip install -U .\PyICU‑2.2‑cp37‑cp37m‑win_amd64.whl

For the record:
My system (Win 10, 64 bit, python 3.8) gave me the exact same error message.
The solution was to install the 32-bit version of the PyICU whl file, not the 64 bit version.
