I was addicted to trying Cython with PyCharm, so make a note

Overview

Trying to use Cython in PyCharm,

  1. Basic Tutorial — Cython 0.29a0 documentation
  2. Easy to build Cython on PyCharm – Nagakute Parabola Diary

After setting setup.py and executing it, referring to

/Users/username/PycharmProjects/cyyc/venv/bin/python3.6 /Users/username/PycharmProjects/cyyc/setup.py build_ext --inplace
Traceback (most recent call last):
  File "/Users/username/PycharmProjects/cyyc/setup.py", line 8, in <module>
    ext_modules=cythonize("helloworld.pyx")
  File "/Users/username/PycharmProjects/cyyc/venv/lib/python3.6/site-packages/Cython/Build/Dependencies.py", line 897, in cythonize
    aliases=aliases)
  File "/Users/username/PycharmProjects/cyyc/venv/lib/python3.6/site-packages/Cython/Build/Dependencies.py", line 777, in create_extension_list
    for file in nonempty(sorted(extended_iglob(filepattern)), "'%s' doesn't match any files" % filepattern):
  File "/Users/username/PycharmProjects/cyyc/venv/lib/python3.6/site-packages/Cython/Build/Dependencies.py", line 102, in nonempty
    raise ValueError(error_msg)
ValueError: 'helloworld.pyx' doesn't match any files

Process completed with exit code 1

I was told that helloworld.pyx could not be found. (" Cyyc " is the project name)

environment

macOS High Sierra 10.13.6 PyCharm Professional 2018.2 (Japaneseized with Pleiades) Python3.6 Use virtualenv

What i did

Specify the absolute path

Made the location of the .pyx file an absolute path.

setup.py


from distutils.core import setup
from Cython.Build import cythonize

setup(
    ext_modules=cythonize("/Users/username/PycharmProjects/cyyc/helloworld.pyx")
)

It was successful, but this is inconvenient.

Change working directory

Review the settings of external tools. PyCharm> Preferences> Tools> External Tools スクリーンショット 2018-09-03 23.11.39.png

The working directory is / venv / bin by default, but change it to the directory containing the source files. Here, for the time being, specify the project directory $ Projectpath $ with a macro. As I noticed later, Referenced site 2 also set it like this. スクリーンショット 2018-09-03 23.58.40.png

Restored setup.py.

setup.py


from distutils.core import setup
from Cython.Build import cythonize

setup(
    ext_modules=cythonize("helloworld.pyx")
)

When executed, a .so file was generated.

What I noticed

Maybe because the first argument is specified as FilePath in the macro in the external tool settings, if you execute the external tool with a file other than ** setup.py ** open, that file will be the argument Is put in and fails to execute.
