tried your code

[loomanss]

didn't work on the first try.

did some code changes but i'm new to python so i cannot estimate the impact on the project:

line 60 changed : for model_name in networkx.topological_sort(g):
new version networkx didnt accept reversed=true argument
line 157 & 158 changed :

parser.add_argument('json_schema_file', type=argparse.FileType('r') , help="Path to JSON Schema file to load")
parser.add_argument('-o', '--output-file', type=argparse.FileType('w'), help="Path to file output", default="model.py")

Name: argparse
Version: 1.2.1

Name: networkx
Version: 2.2

example schema.json used :

{
"definitions": {
"address": {
"type": "object",
"properties": {
"street_address": { "type": "string" },
"city": { "type": "string" },
"state": { "type": "string" }
},
"required": ["street_address", "city", "state"]
}
}
}
