为什么得到一个意外的关键字参数“num\u workers”，其类型为错误：\uuuu init\uuuu（）？

Question

from nornir import InitNornir
from nornir_napalm.plugins.tasks import napalm_get
from nornir_utils.plugins.functions import print_result
import json

def prettyPrintDictionary(dict):
  print(json.dumps(dict, indent=2))


nr = InitNornir(config_file="/home/python/nornir-scripts/config.yaml")

print(nr.inventory.hosts)


prettyPrintDictionary(nr.inventory.get_hosts_dict())

# config.yaml
inventory:
  plugin: SimpleInventory
  options:
    host_file: '/home/python/nornir-scripts/inventory/hosts.yaml'
    group_file: '/home/python/nornir-scripts/inventory/groups.yaml'
    defaults_file: '/home/python/nornir-scripts/inventory/defaults.yaml'
runner:
   plugin: threaded
   options:
     num_workers: 100

请帮助我，我不明白如何初始化nornir 我试着用指南来做，但也有错误。 现在我犯了这个错误

根据documentation，num_workers键应该在runner.options键的内部。将其添加到options键，然后重试：

inventory:
  plugin: nornir.plugins.inventory.simple.SimpleInventory
  options:
    host_file: 'inventory/hosts.yaml'
    group_file: 'inventory/groups.yaml'
    defaults_file: 'inventory/defaults.yaml'
runner:
   plugin: threaded
   options:
     num_workers: 100
