python3 - 无法将'bytes'对象隐式转换为str

Question

我正在尝试通过套接字连接发送列表，但遇到Can't convert 'bytes' object to str 错误。

while True:
    try: 
        data = stream.read(CHUNK)
    except IOError: 
        pass
    else:
        decoded = numpy.fromstring(data, dtype=numpy.float32)
        i = json.dumps(decoded.tolist())
        jsonDecoded = json.loads(i)
        jsonS = "%s" % jsonDecoded
        ws.send(jsonS)

我还尝试了jsonS = "{}".format(jsonDecoded, 'utf-8') 和"".join(str(x) for x in jsonDecoded)，这给了我同样的错误。 str(jsonDecoded, 'utf-8') 也不起作用。

有什么想法吗？

这是完整的堆栈跟踪
