Anki Vector SDK

ertsmal gleich Probleme mit Python

python3 -m pip install --user anki_vector

wirft eine Fehler wegen fehlendem Pket ffi und übersetzt deshalb Paket Cryotography nicht

sudo apt-get install libffi-dev

Die Zeile

python3 -m anki_vector.configure

führt zu

 from . import _methods
  File "/home/dab/.local/lib/python3.6/site-packages/numpy/core/_methods.py", line 158, in <module>
    _NDARRAY_ARRAY_FUNCTION = mu.ndarray.__array_function__
AttributeError: type object 'numpy.ndarray' has no attribute '__array_function__

Mehrere Python-Version auf dem PC

Anki Vector läuft prinzipiell nur mit Python 3.6. Auf dem PC waren aber noch 2.7 aus ROS Kinetic und 3.5 von QNAP installiert. Beim Starten von python3.6 01_hello_world.py kam die Fehlermeldung:

cannot import module

der Grund: er sucht im falschen Pfad Im Python-Interpreter

import cv2
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: /opt/ros/kinetic/lib/python2.7/dist-packages/cv2.so: undefined symbol: PyCObject_Type

Warum suchte er in diesem Pfad? Weil

>>> import sys
>>> print (sys.path)
['', '/opt/ros/kinetic/lib/python2.7/dist-packages', '/usr/lib/python36.zip', '/usr/lib/python3.6', '/usr/lib/python3.6/lib-dynload', '/home/admin/.local/lib/python3.6/site-packages', '/usr/local/lib/python3.6/dist-packages', '/usr/lib/python3/dist-packages']

Den Pfad zu 2.7 ist als erste in der Liste, indem auch das opencv-Modul aus der ROS-Installation liegt, das aber offenbar nicht alle erwarteten Funktionen erhält. Abhilfe: Den Pfad zu 3.6 an erster Stelle setzen!

sys.path.insert(0,"/home/admin/.local/lib/python3.6/site-packages")

dann sieht es folgendermaßen aus:

>>> print(sys.path)
'/home/admin/.local/lib/python3.6/site-packages', '', '/opt/ros/kinetic/lib/python2.7/dist-packages', '/usr/lib/python36.zip', '/usr/lib/python3.6', '/usr/lib/python3.6/lib-dynload', '/home/admin/.local/lib/python3.6/site-packages', '/usr/local/lib/python3.6/dist-packages', '/usr/lib/python3/dist-packages']

Installation von Modulen

Beim Installieren der Module muss man explizit so vorgehen

python3.6 -m pip --user anki_vector

und

python3.6 -m pip opencv-python

weil pip3 install opencv-python leider unter home/admin/.local/lib/python3.5/site-packages installiert. Python 3.6 als Standard per update-alternatives zu setzen, könnte auch funktionieren.... Einzelheiten auch hier Installing Python Modules
