Quitting pySR
shikharmittal04 opened this issue · comments
Describe the bug
I have been trying the example given in the introduction section. Equations were printed after the command model.fit(X, y). However, I am facing the relatively simple issue of quitting the run. As given in the docs, I type q and press enter but nothing happens after that. Am I misinterpreting something?
The following message appeared before equations were printed

/home/shikhar/.local/lib/python3.8/site-packages/pysr/sr.py:291: UserWarning:
Your Python version is statically linked to libpython. For example, this could be the python included with conda, or maybe your system's built-in python.
This will still work, but the precompilation cache for Julia will be turned off, which may result in slower startup times on the initial pysr() call.
To install a Python version that is dynamically linked to libpython, pyenv is recommended (https://github.com/pyenv/pyenv).
To silence this warning, you can run pysr.silence_julia_warning() after importing pysr.

Additional context
I am trying this example on the terminal directly.
Is this in ipython or python?
Could you try typing q, then <enter> multiple times?
I note that the quit won't happen immediately; it will take up to a couple seconds to quit, so that the backend has time to collect the current populations.
I also wonder if it could be because your python is statically linked to libpython - maybe julia can't read stdin when this happens? If other things don't work, you could try setting up a dynamically linked python with:
PYTHON_CONFIGURE_OPTS="--enable-shared" pyenv install 3.9.10(after installing pyenv).
I am using python. Thanks for the suggestions. I installed pyenv following the procedure on the page https://www.liquidweb.com/kb/how-to-install-pyenv-on-ubuntu-18-04/.
I also did PYTHON_CONFIGURE_OPTS="--enable-shared" pyenv install 3.9.10 but I still get the same warning. And q +enter doesn't quit the run.
I'm not sure where this error is coming from, sorry. If I could reproduce it I could take a look at this but I don't see this behavior on any of my machines so I'm not sure where to start. Maybe you could try to write a python unittest for this?
Here are the current tests:
https://github.com/MilesCranmer/PySR/blob/master/test/test.py
The run on ubuntu, macOS, and Windows. If a test breaks on one of these systems, I can try to debug it from there?
Hi, I have to run this code as it is, right? Should there be any output or something, because the code did run with no errors?
Oh, sorry, what I mean is to try to add a new test to test.py that tests the behavior you've seen. It would basically need to manually send 'q' through stdin to stop a test early.
This is a bit of work but I don't have the time to add it right now. I can look later, but in the meantime, if you would like, you could try setting this up?
