Share New Research 
Hi,
I'm trying to set up a research environment on my mac using the Lean CLI as explained here :
The docker container with the jupyter notebook is started, I connect my VS code to the running jupyter server and select the Py-Foundation kernel. However, after running the first cell I get the following issue:
I also tried pulling specifically the research image like this “docker pull --platform linux/amd64 quantconnect/research:latest” but the issue remained.
Would someone have an idea as to why this is happening and how to solve it?
And btw running backtests locally with Lean CLI works for me, so this is only related to the research image.
Thanks!

I figured out the issue. I should have of course used the linux/arm64 platform, so the following works:
docker pull --platform linux/arm64 quantconnect/research:15200
lean research “<project>” --image quantconnect/research:15200
Unfortunately, the latest images on dockerhub only support the amd architecture and 15200 is the latest tag which included the arm architecture. It was pushed around 2 months ago. Is there a reason why the arm builds were discontinued?

For some reason talib is not installed in the research image. So I tried to build a custom image following this discussion:
But there is an error during the lean build command saying that there is no DockerfileLeanFoundationARM file. The dockerfile for that lean arm foundation is indeed not in the Lean repo anymore.

I see it was removed in this PR
Does it mean that arm compatibility has been removed?
