Question

我正在尝试构建一个Docker映像并使用Requirements.txt文件安装这些要求：

numpy==1.18.1
scipy==1.2.1
joblib==0.13.2
Cython==0.29.13
pandas==0.25.3
scikit-learn==0.21.3
h5py==2.8.0
Keras==2.3.1
Keras-Applications==1.0.8
Keras-Preprocessing==1.1.0

这是我的dockerfile：

FROM python:3

MAINTAINER author@sample.com

RUN mkdir /test
COPY ./ /test
WORKDIR /test

## Install your dependencies here using apt-get etc.


RUN pip install -r requirements.txt

当我尝试构建时，这是我收到的错误消息

ERROR: Command errored out with exit status 1:

      from numpy.distutils.core import setup
  ModuleNotFoundError: No module named 'numpy'
  ----------------------------------------
  ERROR: Failed building wheel for scipy

此后，它还会尝试运行

Running setup.py clean for scipy

但没有成功

不确定是不是错误的原因，但考虑到release notes of Numpy 1.18.1，您应该使Cython≥0.29.14，而requirements.txt指定Cython==0.29.13。

FROM python:3可获取Python 3.8。

此版本中支持的Python版本为3.5-3.8。下游开发人员应使用Cython> = 0.29.14获得Python 3.8支持，并且 OpenBLAS> = 3.7，以避免Skylake体系结构上的错误。

scipy的构建轮（setup.py）：状态为“错误”
