运行Docker映像时出错。 没有显示名为cv2，request，boto3的模块

Question

#!/usr/bin/env python
from time import sleep
import datetime
import os
import shutil
import cv2
import io
import numpy as np
import glob
from threading import Thread
import urllib2
import requests
import json
import boto3
import datetime 

I am not able to run my script on docker as I am not able to run modules like cv2 , numpy , requests and boto3 . It works perfectly when I run it on terminal but when I run it as docker image it is showing error that no modules named ... How can i make it run on my docker?

Dockerfile:

FROM resin/raspberry-pi-python:latest
RUN mkdir /myscript
WORKDIR /myscript
COPY capturing.py .
CMD ["/myscript/capturing.py", "-flag"]

Answer 1

You can run your container:

docker run -it <image_name>

and execute the following command in python console that will install specified packages in your container:

import os
os.system("pip install --upgrade pip")
os.system("pip install numpy requests boto3 opencv-python")

You will see:

So all is ok. I tested it in container built using FROM python:latest Dockerfile.
