PyInstaller ImportError DLL not found when testing EXE on other computer

I built an EXE file from a Python script using PyInstaller, using

pyinstaller --onefile myscript.py

Packages I used:

pandas, numpy, imutils, opencv, logging, os, random, json, string, csv, datetime, uuid

The EXE runs fine on my PC. However, when I try it on another PC I get the error shown in this screenshot: https://www.screencast.com/t/msZrURL4v

Any idea what the problem is?
