Я нашел решение.Сначала создайте файл run.py в одном из примеров приложения, которое вы хотите запустить (в папке demos в проекте yowsup) в Visual Studio, и добавьте код для этого файла на основе примера приложения в yowsup wiki (используйте один из кодов run.py из примера приложения).Например:
from layer import EchoLayer
from yowsup.layers import YowParallelLayer
from yowsup.layers.auth import YowAuthenticationProtocolLayer
from yowsup.layers.protocol_messages import YowMessagesProtocolLayer
from yowsup.layers.protocol_receipts import YowReceiptProtocolLayer
from yowsup.layers.protocol_acks import YowAckProtocolLayer
from yowsup.layers.network import YowNetworkLayer
from yowsup.layers.coder import YowCoderLayer
from yowsup.stacks import YowStack
from yowsup.common import YowConstants
from yowsup.layers import YowLayerEvent
from yowsup.stacks import YowStack, YOWSUP_CORE_LAYERS
from yowsup.layers.axolotl import AxolotlControlLayer, AxolotlSendLayer, AxolotlReceivelayer
from yowsup.env import YowsupEnv
CREDENTIALS = ("phone", "password") # replace with your phone and password
if __name__== "__main__":
layers = (
EchoLayer,
YowParallelLayer([YowAuthenticationProtocolLayer, YowMessagesProtocolLayer, YowReceiptProtocolLayer,
YowAckProtocolLayer]),
AxolotlControlLayer,
YowParallelLayer((AxolotlSendLayer, AxolotlReceivelayer)),
) + YOWSUP_CORE_LAYERS
stack = YowStack(layers)
stack.setProp(YowAuthenticationProtocolLayer.PROP_CREDENTIALS, CREDENTIALS) #setting credentials
stack.setProp(YowNetworkLayer.PROP_ENDPOINT, YowConstants.ENDPOINTS[0]) #whatsapp server address
stack.setProp(YowCoderLayer.PROP_DOMAIN, YowConstants.DOMAIN)
stack.setProp(YowCoderLayer.PROP_RESOURCE, YowsupEnv.getCurrent().getResource()) #info about us as WhatsApp client
stack.broadcastEvent(YowLayerEvent(YowNetworkLayer.EVENT_STATE_CONNECT)) #sending the connect signal
stack.loop() #this is the program mainloop
Сохраните его и затем щелкните правой кнопкой мыши run.py -> Выполнить с отладкой.
