python - "Module "QtQuick" version 2.7 is not installed" Error on Raspberry Pi -


i attempting develop gui python code have written insulin pump. i've been using qt quick seems easiest beginner (it doesn't need super fancy, needs work). although qml script runs fine when try run on computer, when attempt run on raspberry pi, returns error qtquick not installed. i've tried installing of relevant dependencies, nothing clear error message. script i'm using run follows: 

import sys pyqt5.qtwidgets import qapplication, qmainwindow pyqt5.qtcore import qurl pyqt5.qtquick import qquickview   if __name__ == "__main__":      app = qapplication(sys.argv)      view = qquickview()     view.setsource(qurl('mainform.ui.qml'))     view.show()      sys.exit(app.exec_())     app = qapplication(sys.argv)      view = qquickview()     view.setsource(qurl('mainform.ui.qml'))     view.show()      sys.exit(app.exec_())

my qtquick code this. 

import qtquick 2.7 import qtquick.controls 2.2 import qtquick.extras 1.4  rectangle {     property alias mousearea: mousearea      width: 360     height: 360     property alias button2: button2      mousearea {         id: mousearea         enabled: true         anchors.rightmargin: 0         anchors.bottommargin: 0         anchors.leftmargin: 0         anchors.topmargin: 0         anchors.fill: parent           button {             id: button             x: 40             y: 208             width: 68             height: 28             text: qstr("basal")             font.pixelsize: 13             font.capitalization: font.capitalize             enabled: true             visible: true             opacity: 0.5             spacing: -22         }          button {             id: button1             x: 253             y: 208             width: 68             height: 28             text: qstr("bolus")         }           button {             id: button2             x: 130             y: 145             text: qstr("status")             font.bold: true             font.pointsize: 20         }          button {             id: button3             x: 145             y: 208             width: 71             height: 28             text: qstr("settings")             autoexclusive: true         }          image {             id: image             x: 12             y: 38             width: 336             height: 75             source: "../downloads/pump logo.jpg"         }     } }

so, think need differently?

also, after error message worked out, wondering: how integrate existing python functions qtquick code? want have user press button, gui change new window , specified function run, output being printed new screen. apologies if dumb question, i'm high schooler , no 1 know knows how code. thank in advance!

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now
