Async exchange issue when loading markets

• OS: Windows 10
• Programming Language version: Python 3.7
• CCXT version: 1.18.208
• Method: load_markets

Code concerned:

class ExchangeCCXTPublic(metaclass=Singleton):
    def __init__(self, exchange_name):
        self.exchange = getattr(ccxta, exchange_name)({"nonce": lambda: ccxt.Exchange.milliseconds()})
        asyncio.run(self.exchange.load_markets())
        self.markets = list()

Stack Trace:

@kroitor I got it worked out. Sorry for the late reply! It was some code before this, thank you.

Update: I used gevent.spawn to download order book for 5 symbols concurrently and it took about 0.8 seconds. So it is clear that the issue doesn’t lie with the way requests are being sent to the exchange. So there is likely an issue with the way I was using asyncio as I still don’t understand it properly or it’s the way I am dealing with ccxt async integration…
