Expected Behavior

When supplying verbose=False to Llama, the model should load as expected.

Current Behavior

When verbose=False, the model fails to load:

from llama_cpp import Llama
llm = Llama(model_path='/tmp/model.gguf', verbose=False)
# ERROR:
# [/usr/local/lib/python3.10/dist-packages/llama_cpp/utils.py](https://localhost:8080/#) in __enter__(self)
#      9         self.errnull_file = open(os.devnull, "w")
#     10 
#---> 11         self.old_stdout_fileno_undup = sys.stdout.fileno()
#     12         self.old_stderr_fileno_undup = sys.stderr.fileno()
#     13 

#UnsupportedOperation: fileno

Environment and Context

The problem happens on Google Colab and a user reported this problem occurring on Windows 11, as well. Doesn't seem to happen on Ubuntu (or Ubuntu in WSL), though.
