在Azure函数中安装requirements.txt时，无法解决对numpy的依赖

Question

我的azure函数使用python模块pywavelets，它需要依赖于numpy。这是我的requirements.txt

azure-functions

cloudpickle==0.5.3
cycler==0.10.0
dask==0.18.2
decorator==4.3.0
kiwisolver==1.0.1
matplotlib==2.2.3
networkx==2.1
numpy==1.15.0
Pillow==5.2.0
pyparsing==2.2.0
python-dateutil==2.7.3
pytz==2018.5
PyWavelets==0.5.2
scikit-image==0.14.0
scipy==1.1.0
six==1.11.0
termcolor==1.1.0
toolz==0.9.0
wget==3.2
nltk
pdfminer
sumy

但是，当在本地测试函数时，我遇到了来自ModuleNotFound的pywavelets错误：

但是我们可以从输出中看到，numpy是在PyWavelets之前安装的。

我如何解决这个问题？事先非常感谢！

更新

下面是我的代码中唯一的python脚本__init__.py：

import logging

import azure.functions as func


def main(req: func.HttpRequest) -> func.HttpResponse:
    logging.info('This function processes a request.')
    # I comment out all the remaining stuff

Answer 1

我使用与您在requirements.txt中相同的模块在我的一侧进行测试，并使用Ctrl + F5运行函数。它显示了与您提到的相同的错误消息。

这两个模块似乎存在一些冲突(在您在requirements.txt中指定的版本中)。要解决这个问题，只需删除requirements.txt中两个模块的版本即可。下面是我的requirements.txt

如果我们不指定版本，它将自动安装最新版本。在我的函数应用程序中，它使用numpy 1.20.0和PyWavelets 1.1.1，当我使用Ctrl + F5时，该函数运行成功。
