我正在从开发容器中运行一些非常基本的python代码
我想让它与numpy一起使用
在我尝试使其与numpy一起使用之前,evrything可以正常工作。
我在python代码中写了这一行:import numpy as np
这些是我在容器中安装numpy的步骤:
我在dockerfile中为numpy添加了pip install:(pip install numpy==1.14.3
有和没有版本...)我收到此错误:
import numpy as np
ModuleNotFoundError: No module named 'numpy'
我尝试在requirements.txt和COPY requirements.txt /tmp/pip-tmp/
dockerfile中添加numpy
这是我的Dockerfile:
FROM python:3
# Avoid warnings by switching to noninteractive
ENV DEBIAN_FRONTEND=noninteractive
# This Dockerfile adds a non-root user with sudo access. Use the "remoteUser"
# property in devcontainer.json to use it. On Linux, the container user's GID/UIDs
# will be updated to match your local UID/GID (when using the dockerFile property).
# See https://aka.ms/vscode-remote/containers/non-root-user for details.
ARG USERNAME=vscode
ARG USER_UID=1000
ARG USER_GID=$USER_UID
# Uncomment the following COPY line and the corresponding lines in the `RUN` command if you wish to
# include your requirements in the image itself. It is suggested that you only do this if your
# requirements rarely (if ever) change.
COPY requirements.txt /tmp/pip-tmp/
# Configure apt and install packages
RUN apt-get update \
&& pip install numpy==1.14.3 \
&& apt-get -y install --no-install-recommends apt-utils dialog 2>&1 \
#
# Verify git, process tools, lsb-release (common in install instructions for CLIs) installed
&& apt-get -y install git openssh-client iproute2 procps lsb-release \
#
# Install pylint
&& apt-get -y install libc-dev \
&& apt-get -y install build-essential \
&& pip install -U pip \
&& pip --disable-pip-version-check --no-cache-dir install pylint \
#&& pip install --no-cache-dir numpy scipy pandas matplotlib \
#
# Update Python environment based on requirements.txt
&& pip --disable-pip-version-check --no-cache-dir install -r /tmp/pip-tmp/requirements.txt \
&& rm -rf /tmp/pip-tmp \
#
# Create a non-root user to use if preferred - see https://aka.ms/vscode-remote/containers/non-root-user.
&& groupadd --gid $USER_GID $USERNAME \
&& useradd -s /bin/bash --uid $USER_UID --gid $USER_GID -m $USERNAME \
# [Optional] Add sudo support for the non-root user
&& apt-get install -y sudo \
&& echo $USERNAME ALL=\(root\) NOPASSWD:ALL > /etc/sudoers.d/$USERNAME\
&& chmod 0440 /etc/sudoers.d/$USERNAME \
#
# Clean up
&& apt-get autoremove -y \
&& apt-get clean -y \
&& rm -rf /var/lib/apt/lists/*
# Switch back to dialog for any ad-hoc use of apt-get
ENV DEBIAN_FRONTEND=dialog
我有同样的错误
(我建立了容器,并在每个步骤之后重新运行它)
如果您知道如何帮助我修复它,请告诉我
为确保您未使用其他python环境,请通过安装在容器中创建python虚拟环境python3-virtualenv
。并使用以下命令将其激活。
RUN python3 -m virtualenv --python=/usr/bin/python3 /opt/venv
ENV PATH="/opt/venv/bin:$PATH"
如果问题仍然存在,请尝试手动删除容器映像并重新创建它。
