unhashable definitions in schema

[AntoineD]

Hi,

I've created a schema with a definitions section, but jsonschema 3.0.1 cannot deal with it. Here is a reproducer :

schema.json contains (from here):

{
    "type": "array",
    "items": { "$ref": "#/definitions/positiveInteger" },
    "definitions": {
        "positiveInteger": {
            "type": "integer",
            "exclusiveMinimum": 0
        }
    }
}

Test code:

import jsonschema
import json
schema = json.load(open('schema.json'))
jsonschema.Draft7Validator({}, schema)

I get this exception:

  File "/xxx/lib/python3.6/site-packages/jsonschema/validators.py", line 276, in __init__
    _generate_legacy_type_checks(types),
  File "/xxx/lib/python3.6/site-packages/jsonschema/validators.py", line 83, in _generate_legacy_type_checks
    definitions[typename] = gen_type_check(pytypes)
  File "/xxx/lib/python3.6/site-packages/jsonschema/validators.py", line 71, in gen_type_check
    pytypes = _utils.flatten(pytypes)
  File "/xxx/lib/python3.6/site-packages/jsonschema/_utils.py", line 161, in flatten
    types.add(thing)
TypeError: unhashable type: 'dict'

You're providing two arguments to the validator.

I feel stupid, sorry for the noise.
Thx.
