"""
Client test.

Run server:

python generate.py  --base_model=h2oai/h2ogpt-oig-oasst1-512-6_9b

NOTE: For private models, add --use-auth_token=True

NOTE: --use_gpu_id=True (default) must be used for multi-GPU in case see failures with cuda:x cuda:y mismatches.
Currently, this will force model to be on a single GPU.

Then run this client as:

python src/client_test.py



For HF spaces:

HOST="https://h2oai-h2ogpt-chatbot.hf.space" python src/client_test.py

Result:

Loaded as API: https://h2oai-h2ogpt-chatbot.hf.space ✔
{'instruction_nochat': 'Who are you?', 'iinput_nochat': '', 'response': 'I am h2oGPT, a large language model developed by LAION.', 'sources': ''}


For demo:

HOST="https://gpt.h2o.ai" python src/client_test.py

Result:

Loaded as API: https://gpt.h2o.ai ✔
{'instruction_nochat': 'Who are you?', 'iinput_nochat': '', 'response': 'I am h2oGPT, a chatbot created by LAION.', 'sources': ''}

NOTE: Raw output from API for nochat case is a string of a python dict and will remain so if other entries are added to dict:

{'response': "I'm h2oGPT, a large language model by H2O.ai, the visionary leader in democratizing AI.", 'sources': ''}
