Missing Variable: Variable os does not exist

[rhr]

I get the error message "Missing Variable: Variable os does not exist" when trying to execute anything in a Jupyter notebook cell with this kernel

I can look into this Friday. What OS, Python Version and Jupyter version do you have?

I just realized that this error does not prevent cell execution, so is not a showstopper. In any case all the components were installed through conda yesterday (Jan 20). Thanks!

Ubuntu 20.04, python 3.9

jupyter core : 4.7.0
jupyter-notebook : 6.2.0
ipython : 7.19.0
ipykernel : 5.4.2
jupyter client : 6.1.11
jupyter lab : 3.0.5

I was goofing around with this, and I think the issue might be if Python doesn't find the path you're trying to write to. I found this issue in the rb_mcmc_demo notebook, in the first cell where it wasn't finding the path to the example files. I didn't get the error after this.

I don't think it's about finding the path. It just seems to appear after the first thing sent to the kernel. I got it using the console and notebook with a simple assignment statement ("mu <- 1")
