setup.py + cython == chicken and the egg problem
Hi folks. I'm attempting to package up a python package that uses Cython. Rather than build binaries for everything under the sun, I've been focusing on including the .pyx file and running cython on it at install time. This requires a C compiler, but I'm OK with that. However, when I try to install the package from test.pypi.org, I get: $ python3 -m pip install -i https://test.pypi.org/simple/ pyx-treap below cmd output started 2022 Tue Aug 16 01:55:16 PM PDT Looking in indexes: https://test.pypi.org/simple/ Collecting pyx-treap Downloading https://test-files.pythonhosted.org/packages/3a/41/af5360934adccfc086a39e1f720323895144b53454ff6dacc0f06267db55/pyx_treap-2.0.15.tar.gz (125 kB) 125.9/125.9 kB 1.9 MB/s eta 0:00:00 Installing build dependencies ... error error: subprocess-exited-with-error ×? pip subprocess to install build dependencies did not run successfully. ?? exit code: 1 > [3 lines of output] Looking in indexes: https://test.pypi.org/simple/ ERROR: Could not find a version that satisfies the requirement setuptools (from versions: none) ERROR: No matching distribution found for setuptools [end of output] note: This error originates from a subprocess, and is likely not a problem with pip. error: subprocess-exited-with-error ×? pip subprocess to install build dependencies did not run successfully. ?? exit code: 1 > See above for output. note: This error originates from a subprocess, and is likely not a problem with pip. But I analyzed the pip install with strace, and found no interesting exec's, and no interesting "= E" patterns. I've tried quite an assortment of things to get past this, including most of those at: https://stackoverflow.com/questions/4996589/in-setup-py-or-pip-requirements-file-how-to-control-order-of-installing-package Except the one at: https://stackoverflow.com/a/54269307/1084684 ...because I was having a "there must be a better way" reaction to it. /Is/ there a better way? There're all these newer ways of doing packaging - surely one of them addresses this problem? The code I'm trying to package is at: https://stromberg.dnsalias.org/svn/treap/trunk/cython BTW, the pure python version works fine, and the cython version works too as long as you preinstall cython - but I don't want users to have to know that :) Thanks! -- https://mail.python.org/mailman/listinfo/python-list

In this case, the dict should just be omitted from 'data'. I can have 'get_job_efficiency_dict' return 'None' and then run filtered_data = list(filter(None, data)) but is there a more elegant way? Just wondering, why don't you return an empty dictionary in case of a failure? In that case your list will be all dictionaries and empty ones will be processed fast enough. When the list of dictionaries is processed, I would have to check each element to see if it is empty. That strikes me as being less efficient than filtering out the empty dictionaries in one go, although obviously one would need to benchmark that. I may be missing something but why would you have to check each element to see if it is empty? What would go wrong if you just treated empty dictionaries the same as non-empty directories?

Re: Problem using cx_Freeze

This is a meaningless bit of information. The most likely __init__() involved is the one where cx_Freeze.Executable is instantiated. https://cx-freeze.readthedocs.io/en/latest/setup_script.html#cx-freeze-executable shows 11 parameters (and "self" would make the 12th). -- Wulfraed Dennis Lee Bieber AF6VN wlfr...@ix.netcom.comhttp://wlfraed.microdiversity.freeddns.org/ -- https://mail.python.org/mailman/listinfo/python-list
