Fail to Install tombo using venv3 Ubuntu18.04

[abadouh]

Hey, I am trying to install tombo using pip and or the git repository and I get the same error. Below you can find the details:

OS: Ubuntu18.04 Python: 3.8 numpy: 1.24.4

Using pip

mkdir tombo 
python3 -m venv venv3
source venv3/bin/activate
pip install --upgrade pip
pip install numpy
pip install ont-tombo[full]

Using github

git clone https://github.com/nanoporetech/tombo 
cd tombo/
python3 -m venv venv3
source venv3/bin/activate
pip install --upgrade pip
pip install numpy
pip install -e .

I get the following error:
