为什么conda安装tk不能在我的docker容器中工作，即使它说安装了？
我在我的python 3 docker容器中遇到了问题。
我试过了：
conda install tk
但它说它确实安装它
root@36602e2cd649:/home_simulation_research/overparametrized_experiments/pytorch_experiments# conda install tk Fetching package metadata ........... Solving package specifications: . # All requested packages already installed. # packages in environment at /opt/conda: # tk 8.6.7 h5979e9b_1
但是当我去python，并尝试导入它不起作用：
>>> import Tkinter Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: No module named 'Tkinter'
和其他错误：
>>> import tkinter Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/opt/conda/envs/pytorch-py35/lib/python3.5/tkinter/__init__.py", line 35, in <module> import _tkinter # If this fails your Python may not be configured for Tk ImportError: libX11.so.6: cannot open shared object file: No such file or directory
当我运行需要它的脚本时：
Traceback (most recent call last): File "bulk_experiment_dispatcher.py", line 18, in <module> from data_file import * File "/home_simulation_research/overparametrized_experiments/pytorch_experiments/data_file.py", line 16, in <module> import matplotlib.pyplot as plt File "/opt/conda/envs/pytorch-py35/lib/python3.5/site-packages/matplotlib/pyplot.py", line 115, in <module> _backend_mod, new_figure_manager, draw_if_interactive, _show = pylab_setup() File "/opt/conda/envs/pytorch-py35/lib/python3.5/site-packages/matplotlib/backends/__init__.py", line 32, in pylab_setup globals(),locals(),[backend_name],0) File "/opt/conda/envs/pytorch-py35/lib/python3.5/site-packages/matplotlib/backends/backend_tkagg.py", line 6, in <module> from six.moves import tkinter as Tk File "/opt/conda/envs/pytorch-py35/lib/python3.5/site-packages/six.py", line 92, in __get__ result = self._resolve() File "/opt/conda/envs/pytorch-py35/lib/python3.5/site-packages/six.py", line 115, in _resolve return _import_module(self.mod) File "/opt/conda/envs/pytorch-py35/lib/python3.5/site-packages/six.py", line 82, in _import_module __import__(name) File "/opt/conda/envs/pytorch-py35/lib/python3.5/tkinter/__init__.py", line 35, in <module> import _tkinter # If this fails your Python may not be configured for Tk ImportError: libX11.so.6: cannot open shared object file: No such file or directory
我尝试apt-get install python-tk （从安装tkinter for Python ），但它没有工作：
root@36602e2cd649:/home_simulation_research/overparametrized_experiments/pytorch_experiments# apt-get install python-tk Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package python-tk
我试着运行ENTERYPOINT作为build议的答案之一，但它扔了我一些更多的错误：
/path/fake_gui.sh: 8: /home_simulation_research/overparametrized_experiments/docker_files/runtime/fake_gui.sh: source: not found /path/fake_gui.sh: 12: /home_simulation_research/overparametrized_experiments/docker_files/runtime/fake_gui.sh: function: not found /path/fake_gui.sh: 13: kill: invalid signal number or name: SIGTERM /path/fake_gui.sh: 15: /home_simulation_research/overparametrized_experiments/docker_files/runtime/fake_gui.sh: Syntax error: "}" unexpected
但不知道该怎么办…
有用的问题：
如何在我的泊坞窗图像中安装python-tk
您需要使用已安装并运行虚拟帧缓冲区的Docker容器。
这篇博客文章解释了将X11放入docker集装箱的“为什么和如何”。
您可以通过他们的entry_point.sh在Selenium Docker容器中看到他们是如何entry_point.sh ：
#!/bin/bash # # IMPORTANT: Change this file only in directory Standalone! source /opt/bin/functions.sh export GEOMETRY="$SCREEN_WIDTH""x""$SCREEN_HEIGHT""x""$SCREEN_DEPTH" function shutdown { kill -s SIGTERM $NODE_PID wait $NODE_PID } if [ ! -z "$SE_OPTS" ]; then echo "appending selenium options: ${SE_OPTS}" fi SERVERNUM=$(get_server_num) rm -f /tmp/.X*lock xvfb-run -n $SERVERNUM --server-args="-screen 0 $GEOMETRY -ac +extension RANDR" \ java ${JAVA_OPTS} -jar /opt/selenium/selenium-server-standalone.jar \ ${SE_OPTS} & NODE_PID=$! trap shutdown SIGTERM SIGINT wait $NODE_PID
上面代码的源代码来自于GitHub， SeleniumHQ / docker-selenium上的这个仓库。
用python 3，你必须导入如下：
import tkinter # with a small caps 't'
好吧，所以一旦我把一个虚拟屏幕的图像停止崩溃：
RUN apt-get update RUN apt-get install -y xvfb #RUN Xvfb :1 -screen 0 1024x768x16 &> xvfb.log &
当我跑我的docker形象。
