The errors imply you are missing a bunch of pre-reqs, including a fortran compiler. You will need to go through the pre-requists for all the nodes you want to install and make sure you install all the libraries/tools they need before trying to install the nodes. Doing this by hand in a shell attac…

Yes - you need python and panda inside the container. As you are running a VM do you need really need to run inside docker as well ? If you really need it in a container you may be best building your own container either based off the existing image or using the customisable docker-custom image in o…

Based on the page you provided, this command: docker run -it -p 1880:1880 -v node_red_data:/data --name mynodered nodered/node-red:latest which doesn't specify the "image-type", I believe that it will be "none" by default". So can somehow check that I have Python?

[image] s19k15: "I believe that it will be "none" by default". So can somehow check that I have Python? ----Update---- I managed to attach the terminal and check that I have python sudo docker exec -it mynodered bash python3 --version -> 3.8.2 python --version -> 2.7.18 So the python ca…

correct as they are extra packages that need to be installed.

So how can I install these extra packages inside the container? I tried already via bash without success... python3 -m pip install numpy python3 -m pip install pandas

An alternative is not to use the python-function nodes (which I think others have had trouble with), write your functions in javascript instead, or use an exec node to call out to python scripts.

Hi, I am using only machine-learning nodes in the flow. [image] I just installed the python functions to make sure that are not prerequisites.

OK, I misunderstood, I thought it was the python function nodes that were causing the problem. You can take those out if you are not using them.

That's true, I can remove them or leave them for feature building. But what about the issue of machine-learning node? How can I install the pandas and other packages inside the container?

Can't help with that one I am afraid, I don't know much about Docker.
