Shapely: vectorizado en Python 3.8

@mikedh, ¿estás intentando instalar pip de forma adecuada en un entorno conda? Veo una pista de eso en https://travis-ci.org/mikedh/trimesh/jobs/627984786#L1048. Si bien esto puede funcionar para paquetes de python puro, no puede funcionar para paquetes que incluyen módulos de extensión como lo hace Shapely. Simplemente no puede instalar por pip las ruedas bien formadas en PyPI en un entorno de conda, debe ponerse bien de un canal de conda como conda-forge.

Sí, pip install en conda python es un poco extraño, pero creo que el problema está en otra parte y es reproducible en la línea principal de Python. Aquí hay un Dockerfile de reproducción mínimo:

FROM python:3.8-slim-buster
RUN apt-get update; apt-get install -y libgeos-dev
RUN pip install numpy shapely
RUN python -c "from shapely import vectorized"

Falla con:

Step 4/4 : RUN python -c "from shapely import vectorized"
 ---> Running in 9f5d06d595d1
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/local/lib/python3.8/site-packages/shapely/vectorized/__init__.py", line 3, in <module>
    from ._vectorized import (contains, touches)
ModuleNotFoundError: No module named 'shapely.vectorized._vectorized'
The command '/bin/sh -c python -c "from shapely import vectorized"' returned a non-zero code: 1

Hice un poco de depuración y probé algunas cosas, ninguna de las cuales funcionó. Como referencia, aquí hay un Dockerfile un poco más útil:

FROM python:3.8-slim-buster
RUN apt-get update; apt-get install -y  --no-install-recommends git libgeos-dev
RUN pip install numpy cython
# COPY Shapely Shapely
RUN git clone https://github.com/Toblerity/Shapely.git
RUN cd Shapely; python setup.py install
RUN python -c "from shapely import vectorized"

Y el resultado completo de los pasos de construcción bien formados:

Step 4/6 : RUN git clone https://github.com/Toblerity/Shapely.git
 ---> Running in 89f7b2d15e03

@mikedh gracias por ser paciente y persistente. Encontré el problema.

La distribución fuente Shapely 1.6.4.post2 (sdist) es defectuosa y no incluye un archivo _vectorized.c.

$ tar tzvf ~/Downloads/Shapely-1.6.4.post2.tar.gz | grep "\.c$"

La bien formada 1.7a2 sdist lo hace.

¿Estarías dispuesto a probar la versión preliminar de 1.7a2? Está en buena forma, en mi opinión. Tiene muchos menos errores conocidos que 1.6.4.post2, y parece estar sirviendo bastante bien a los usuarios de geopandas. Si no es así, puede probar Python 3.7, tenemos ruedas binarias en PyPI para py37 y bien proporcionado 1.6.4.post2.

¡Gracias por rastrear esto! Sí, parece que 1.7a2 hace el truco .

Un poco extraño que fuera reproducible incluso cuando se construía a partir de un clon del repositorio, ¿tal vez faltaban los encabezados geos o algo así? Siéntase libre de cerrar, o podemos esperar a que se cierre el lanzamiento.

Para otras personas que quieran el prelanzamiento, pueden instalarlo con:
pip install shapely==1.7a2

Usuario de Trimesh aquí, este hilo me salvó el día.

¡Apoyos para los colaboradores de la versión 1.7.0, incluida la corrección!
