[英]Can't import my compiled cython module in docker
I can successfully compile my cython module on windows (visual studio) and run python code that uses the cython module.我可以在 windows (visual studio) 上成功编译我的 cython 模块并运行使用 cython 模块的 python 代码。
I can successfully compile my cython module on linux (gcc/Docker container), but I get a ModuleNotFoundError when I run the same python code that works on windows.我可以在 linux(gcc/Docker 容器)上成功编译我的 cython 模块,但是当我运行在 Windows 上运行的相同 python 代码时,我得到一个 ModuleNotFoundError 。
Here is my project structure on linux.这是我在 linux 上的项目结构。 When I compile it puts the .so file at /engine for some reason (doesn't do this on windows).
当我编译时,它出于某种原因将 .so 文件放在 /engine 中(在 Windows 上不这样做)。 So this is the structure after I move it to the proper spot in bbmajors_compute/compute_engine/engine:
所以这是我将其移动到 bbmajors_compute/compute_engine/engine 中适当位置后的结构:
+-- bbmajors_compute
| +-- compute_engine
| | +-- engine
| | | +-- __init__.py
| | | +-- compute_cpp.pyx
| | | +-- compute_cpp.pxd
| | | +-- compute_cpp.cpp
| | | +-- compute_cpp.cpython-37m-x86_64-linux-gnu.so
| | +-- __init__.py
| | +-- views.py
+-- __init__.py
+-- setup.py
Here is my setup.py:这是我的 setup.py:
from distutils.core import setup
from Cython.Build import cythonize
setup(ext_modules=cythonize("bbmajors_compute/compute_engine/engine/compute_cpp.pyx"))
Here is the build command:这是构建命令:
python ./setup.py build_ext --inplace
Here is the code trying to import the cython module (last line is one that gives error):这是尝试导入 cython 模块的代码(最后一行是错误的):
from django.shortcuts import render
from django.shortcuts import redirect
from django.http import HttpResponseRedirect
from django.http import JsonResponse
from django.contrib.auth.decorators import login_required
from .forms import TeamForm
from .engine.player_costs_handler import create_costs_dict
from .engine.player_stats_handler import create_stats_dict
from .engine.player_merge_handler import merge_player_data, create_results_dict
# Cython modules
from .engine.compute_cpp import CalculateCombinationsCpp
Here is the error:这是错误:
web_1 | File "/code/bbmajors_compute/compute_engine/views.py", line 14, in <module>
web_1 | from .engine.compute_cpp import CalculateCombinationsCpp
web_1 | ModuleNotFoundError: No module named 'bbmajors_compute.compute_engine.engine.compute_cpp'
Any help is appreciated!任何帮助表示赞赏! I've been looking at this for a while...
我已经看这个有一段时间了...
I was having a similar issue for a while and just about pulling my hair out trying to solve it.我有一段时间遇到类似的问题,只是想把头发拉出来试图解决它。 Luckily I came across this gist which proved very helpful.
幸运的是,我遇到了这个被证明非常有帮助的要点。
The solution may be for you to add the following line to your Dockerfile.解决方案可能是将以下行添加到 Dockerfile。
RUN python setup.py build_ext --inplace
