I had the same issue. I modified sentence.py file from library. Added lines with **. Seems to fix this but I don’t know about any other side effects

def get_api_format(self):
    formated = [self.path + self.command]
    for key, value in self.attributes.items():
        **if type(value) == str:**
            **value = str.encode(value)**
        formated.append(b'=' + key + b'=' + value)
    for query in self.queries:
        formated.extend(query.get_api_format())
    if self.tag is not None:
        formated.append(b'.tag=' + self.tag)
    return formated

Two parts to the answer:

Simple way to make it work is to change the fields to bytes, like this:

import routeros_api as routers

connection = routers.RouterOsApiPool('IP', username='username', password='password')
api = connection.get_api()
api.get_binary_resource('/').call('ping', { 'address': b'192.168.56.1', 'count': b'4' }) #this ip i got from example

However, it does raise the question about whether under Python3 that we should be handling better.
