hi, few days ago i have been testing medgemma-27b text only version, since gemma3 have built-in function calling capability, i also want to use it in medgemma-27b.
However, i followed most of setup in quick_start_with_hugging_face.ipynb, while a there's repeat thinking issue & trancated bug (max_new_token=1500) in function calling.
Note that i also turn on thinking mode :
if "27b" in model_variant and is_thinking:
thought, response = response.split("") # raise str.split("") giving me "ValueError: empty separator"
thought = thought.replace("thought\n", "")
Function calling have error output (repeated output) as below, and it obviously ends in trancated response (should i set longer max_new_token > 1500 ?)
(Pdb) print(decoded)

The user wants to find the name of a product with the Product ID 807ZPKBL9V. I can use the `get_product_name_by_PID` function to achieve this.
1. **Identify the function:** The user is asking for the product name given the Product ID. The `get_product_name_by_PID` function is designed for this purpose.
2. **Extract the parameter:** The Product ID is provided as "807ZPKBL9V".
3. **Format the function call:** Construct the JSON object with the function name and the parameter.
```json
{"name": "get_product_name_by_PID", "parameters": {"PID": "807ZPKBL9V"}}
```
4. **Output the function call:** Respond with only the JSON object.<unused95>```json
{"name": "get_product_name_by_PID", "parameters": {"PID": "807ZPKBL9V"}}
```thought
