在缓冲区中找不到 Org Babel 源块参数引用

Question

I'm using a python source block to generate graph images from tables for a homework assignment. As documented here , I have a named table which I am making available to the python block as an argument. I got this working, then at some point it stopped working for no obvious reason.

When I try to evaluate the code block, either directly or through a #+call: directive, it fails and generates the following error message:

Reference 'blank_dset' not found in this buffer

Here's the full org file for reference: https://pastebin.com/nS09gX8U

Answer 1

What happened here was that I accidentally marked the headline as a comment , which caused babel to ignore the named tables I was trying to use.
