Shapely: vektorisiert auf Python 3.8

@mikedh versuchen Sie, eine formschöne Installation in einer Conda-Umgebung zu installieren? Einen Hinweis dazu sehe ich unter https://travis-ci.org/mikedh/trimesh/jobs/627984786#L1048. Während dies für reine Python-Pakete funktionieren kann, kann dies nicht für Pakete funktionieren, die Erweiterungsmodule enthalten, wie dies bei Shapely der Fall ist. Sie können die formschönen Räder von PyPI einfach nicht in einer Conda-Umgebung installieren, Sie müssen aus einem Conda-Kanal wie Conda-Forge formschön werden.

Ja, pip install in Conda Python ist etwas seltsam, aber ich denke, das Problem liegt woanders und ist auf Mainline-Python reproduzierbar. Hier ist ein minimal reproduzierendes Dockerfile:

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"

Scheitert mit:

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

Habe ein wenig debuggen und ein paar Dinge ausprobiert, von denen nichts funktioniert hat. Als Referenz ist hier ein etwas nützlicheres Dockerfile:

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"

Und die volle Ausgabe der formschönen Bauschritte:

Step 4/6 : RUN git clone https://github.com/Toblerity/Shapely.git

@mikedh danke für

Die Quelldistribution Shapely 1.6.4.post2 (sdist) ist defekt und enthält keine _vectorized.c-Datei.

Der formschöne 1.7a2 sdist tut es.

Wären Sie bereit, die 1.7a2-Vorabversion auszuprobieren? Es ist meiner Meinung nach in einem guten Zustand. Es hat weit weniger bekannte Fehler als 1.6.4.post2 und scheint den Benutzern von Geopandas recht gute Dienste zu leisten. Wenn nicht, können Sie Python 3.7 ausprobieren, wir haben Binärräder auf PyPI für py37 und formschöne 1.6.4.post2.

Danke, dass du das aufgespürt hast! Yup sieht so aus, als ob 1.7a2 den Trick macht .

Irgendwie seltsam, dass es reproduzierbar war, selbst wenn es aus einem Klon des Repositorys erstellt wurde, vielleicht fehlten die Geos-Header oder so? Fühlen Sie sich frei, zu schließen, oder wir können warten, bis die Veröffentlichung geschlossen ist.

Für andere Leute, die die Vorabversion möchten, können Sie sie mit installieren:
pip install shapely==1.7a2

Trimesh-Benutzer hier, dieser Thread hat mir den Tag gerettet.

Props an die Mitwirkenden für die Version 1.7.0 einschließlich des Fixes!
