pip attempts to run `python setup.py egg_info` to detemine the install requirements. However, now I want to know how best to package it. 2 Inside this file, you can start by writing regular Python code (note that there are some limitations in the Python code accepted by Cython, as clarified in the Cython docs). Instructions for installing from source, PyPI, ActivePython, various Linux distributions, or a development version are also provided. This is the recommended installation method for most users. Cython (writing C extensions for pandas)¶ For many use cases writing pandas in pure Python and NumPy is sufficient. # install a C compiler first pip install cython pip install amortization -v # Add -v to see what is happening behind the scenes To wrap up.

Allow fastparquet to be installed when NumPy and Cython are not already installed. Now that we don't cythonize before creating the sdist, using the sdist fails to properly install the package if the freshly created environment doesn't include scipy. Cython increases the speed of a Python module by compiling a Python code to C. Although this is a common use-case for developers to use Cython, we can use it for code obfuscation.
