One solution to this issue on pyml_bindgen GitHub.
Essentially, it is a way to embed multiple Python files/modules into your OCaml executable.
The py directory has some Python code. Two modules mathy and sparkles, with submodules. interface.py depends on both of them, and that is the file we want to generate bindings for with pyml_bindgen.
The problem is that we don't want to have to have the user of our OCaml program care about installing these modules we made. We want it all embedded. So the stickytape program is used to generate one python script with machinery to "roll up" everything needed into one file. Then this rolled up file is embedded in the OCaml code for pyml to use.
Checkout the dune file for the shell commands needed to set this all up.
Run the executable with dune exec ./yo.exe and the tests with dune runtest. After you build, feel free to move the generated executable to another directory, or another machine, it will work fine!
