python-3.x - 如何修复 TypeError 不可散列类型：'rqm__Cell' ->（自动生成的类）

Question

我正在使用 python-json-schema-objects 从模式中自动生成类。我正在尝试用已经生成的对象填充数组。

但我收到了这个错误 -

TypeError 不可散列类型：'rqm__Cell'

我的问题和错误与此处发布的问题非常相似 https://github.com/cwacek/python-jsonschema-objects/issues/126

这是架构

"rqm__RatType": {
  "type": "string",
  "enum": [
    "GSM",
    "CDMA"
  ]
},
"rqm__ChannelBandwidth": {
  "type": "string",
  "enum": [
    "BW_1_4_MHZ",
    "BW_3_MHZ",
  ]
},
"rqm__Cell": {
  "type": "object",
  "properties": {
    "rat": {
      "$ref": "#/definitions/rqm__RatType"
    },
    "bandwidth": {
      "$ref": "#/definitions/rqm__ChannelBandwidth"
    }
  }
},
"rqm__CellSet": {
  "type": "object",
  "properties": {
    "cellsToDeploy": {
      "type": "array",
      "items": {
        "$ref": "#/definitions/rqm__Cell"
      },
      "minItems": 0,
      "uniqueItems": true
    }
  }
},

我正在使用的代码是

import python_jsonschema_objects as pjs
schema = {}
schema['Rqm'] = 'rqm.json'
builder = pjs.ObjectBuilder(schema['Rqm'])
ns = builder.build_classes()
Cell = ns.RqmCell
CellSet = ns.RqmCellset
cellSet = None
GSMCell = Cell(rat='GSM', bandwidth='BW_1_4_MHZ')
cellSet = CellSet(cellsToDeploy=[GSMCell])

在最后一行我得到这个错误

TypeError 不可散列类型：'rqm__Cell'
