ImportError: Kein Modul mit dem Namen _ctypes. Google App Engine mit Bokeh-Plot

• Python 2.7.13
• Windows 10 64 Bit

Ich habe diesen Udacity web dev course durchgearbeitet und wollte versuchen, ein einfaches Bokeh-Diagramm mit diesem Beispiel in eine Webseite einzubetten. Beim Ausführen von dev_appserver.py wird der Fehler angezeigt: ImportError: No module named _ctypes

Ich habe:

• Installierte Bokeh und Numpy via pip
• Numpy in app.yaml enthalten

Diese Antwort gibt an, dass Google App Engine den Import von C-Typen nicht zulässt. Ich bin mir jedoch nicht sicher, wie ich feststellen kann, ob dies bei Bokeh der Fall ist. Wird dieser Fehler dadurch verursacht, dass Bokeh ctypes importiert? Wenn ja, gibt es eine Arbeit?

UPDATE 1: Ich habe numpy 1.12.0 deinstalliert und numpy 1.6.1 installiert. Ich bekomme jetzt diesen Fehler: 

NP_MS_DELTA = np.timedelta64(1, 'ms')
TypeError: function takes at most 1 argument (2 given)

This states numpy 1.6.1 kann keine Einheit im Skalar-Konstruktor angeben. Bedeutet das, dass Bokeh auf numpy> 1.6.1 setzt?

UPDATE 2:

Das erinnert mich daran, als ich Bokeh installiert habe. Beim Herunterladen seiner Abhängigkeitsanzahl schien es auf numpy> = 1.7.1 zu setzen:

Collecting numpy>=1.7.1 (from Bokeh)
