Why is conda install tk not working in my docker container even though it says it is installed?
I am having problems with tk
in my python 3 docker container.
I tried:
conda install tk
but he says he installed it
root@36602e2cd649:/home_simulation_research/overparametrized_experiments/pytorch_experiments# conda install tk

tk 8.6.7 h5979e9b_1
but when I switch to python and try to import it, it doesn't work:
>>> import Tkinter
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named 'Tkinter'
and other errors:
>>> import tkinter

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
when i run the script it needs:

I tried apt-get install python-tk

I tried running ENTERYPOINT
as one of the suggested answers, but it got me a few more errors:
/path/fake_gui.sh: 8: /home_simulation_research/overparametrized_experiments/docker_files/runtime/fake_gui.sh: source: not found

but not sure what to do ...

You need to use a Docker container with virtual framebuffer installed and running .
This blog post explains the "why and how" of hosting X11 in a docker container.
You can see how they do it in the Selenium Docker container through their 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
