[Bug] The language changes after BootstrapFewShot.

[mhhz]

What happened?

When I normally use "signature" to define my input and output and use COT for prediction, the output is correct and in Chinese. However, after I optimize it using BootstrapFewShot and obtain a JSON model file, why does it output in English when I load this model file and make predictions again, even though the training examples I provided are in Chinese?

Steps to reproduce

COT的结果 Prediction(
reasoning="The current weather is sunny with an outside temperature of 25°C and an inside temperature of 23.5°C. The AC is currently set to heat at 23°C, which is not ideal for a sunny day. The user prefers a temperature of 23°C and a fan speed of 3. The inside air quality is poor (80).
Given the sunny weather and the user's preference, I should switch the AC to cooling mode, increase the fan speed, and potentially enable recirculation to improve air quality. Since the AC is already on and set to 23, I will only adjust the fan speed and switch to cooling.",

reason='The weather is sunny and the current AC setting is heating. Switching to cooling mode and increasing the fan speed will provide a more comfortable environment. Enabling recirculation will help improve the inside air quality.'
