Data Builders Hackathon tips and notes

Historical Transactional Data - Covalent

Hey! We highly recommend using Pockt Network and TrueBlocks to get and index your own data. If you are trying and having problems, please send your questions on our discord. If you realize that this method is not possible for now, @stefi developed a python script to help you get indexed historical transactional data using Covalent, any questions on the this you can reach her, she will be happy to know that you used this :)

Problems running Raphtory: Python version and Windows OS

Hi!, if you're thinking about doing some graph analysis using Raphtory, Windows as your OS and Jupyter Notebook as IDE, I have some tips :)

Raphtory has great documentation, you can find it HERE . One thing you're going to notice is that it only works with 3.10 >= python version <= 3.11 , I had problems updating my Jupyter Notebook to this version, in the end I had to set another virtual environment . If you have the same issue, check this tutorial, it's the greatest I found about the topic:

• Anaconda Virtual Environments and Kernels for Jupyter Notebook

Alright, all set them you run your !pip install pyraphtory and get this error:

‘note: This error originates from a subprocess, and is likely not a problem with pip. error: subprocess-exited-with-error’

Reads better and find these:

'Exception: Unsupported OS. Cannot install.'

Ben, one of the founders, clarified these shouldn’t be happening and will investigate further with the team, apparently the package works better in Linux, so you have the options to create a Windows Subsystem , he indicated these tutorial:

• Configuring Jupyter Notebook in Windows Subsystem Linux (WSL2)

After going through the subsystem tutorial, remember to set your environment to work with the correct python version :) As soon as I have updates I will update these post. if you want to talk with me, ping me on discord, stefi_says#1654 .
