AirLLMLlamaMlx fails to load model with mlx==0.0.7

[jakule]

The sample code (taken from AirLLM examples):

from airllm import AirLLMLlamaMlx
import mlx.core as mx

MAX_LENGTH = 128
model = AirLLMLlamaMlx("garage-bAInd/Platypus2-7B")

input_text = [
    'I like',
]

input_tokens = model.tokenizer(input_text,
                               return_tensors="np",
                               return_attention_mask=False,
                               truncation=True,
                               max_length=MAX_LENGTH,
                               padding=False)

generation_output = model.generate(
    mx.array(input_tokens['input_ids']),
    max_new_tokens=3,
    use_cache=True,
    return_dict_in_generate=True)

print(generation_output)

fails to load the model with

ValueError: [load] Input must be a file-like object, or string

after upgrading to mlx 0.0.7. It works fine with 0.0.6.
