```python
# Python
import json
from prophet.serialize import model_to_json, model_from_json
with open('serialized_model.json', 'w') as fout:
json.dump(model_to_json(m), fout) # Save model
fout.write(model_to_json(m)) # Save model
with open('serialized_model.json', 'r') as fin:
m = model_from_json(json.load(fin)) # Load model
m = model_from_json(fin.read()) # Load model
```
The json file will be portable across systems, and deserialization is backwards compatible with older versions of prophet.
