我建立一个docker
图像数据的科学项目。
我通过RUN apk add <package>
安装核心的依赖。
Dockerfile-dev的

# add and install requirements
COPY ./requirements.txt /usr/src/app/requirements.txt
RUN pip install -r requirements.txt
一切都建立到pandas
,此时这个错误出现:
Complete output from command python setup.py egg_info:
Traceback (most recent call last):

KeyError: 'numpy'
During handling of the above exception, another exception occurred:

ModuleNotFoundError: No module named 'numpy'
----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-v7gyw8y_/pandas/
但numpy
已经预先安装:
运行setup.py安装numpy的:完成与状态“完成”
尚未打败,我搬到pandas==0.20.3
(这个版本在我的畅达py36
ENV工作)到requirements.txt
,它被安装,如日志显示:
Successfully built: pandas
Installing collected packages: pandas
Successfully installed: pandas-0.20.3
经过编译的时候,然而,在运行容器记录以下错误:
users_1 | File "/usr/src/app/project/api/classifiers/metadata/learn.py", line 14, in <module>
users_1 | import pandas as pd
users_1 | ModuleNotFoundError: No module named 'pandas'
所以,它是由pip
安装,但无法找到?
如何安装qazxsw POI通过qazxsw POI为了保持一致性,打造我的数据科学项目?
添加以下行的伎俩对我来说,里面pandas
:
RUN apk add
我必须明确指定Dockerfile-dev
版本。
