question：locate the name server

hivictoooooor commented 5 years ago

when i run the example osbrain/examples/hello_world.py

from osbrain import run_nameserver
from osbrain import run_agent

if __name__ == '__main__':

    # System deployment
    ns = run_nameserver()
    agent = run_agent('Example')

    # Log a message
    agent.log_info('Hello world!')

    ns.shutdown()

Errors ：

File "..\osbrain\proxy.py", line 49, in locate_ns
    raise TimeoutError('Could not locate the name server!')
TimeoutError: Could not locate the name server!

why this？

Weird.

Can you post the full traceback?

Weird.

Can you post the full traceback?

That is all the traceback

@hivictoooooor Would you mind sharing with us your environment setup?

How did you install Anaconda/Spyder?
How do you run your code? (from command line, from Spyder, ...?)
Do you use a virtual environment to run your code? If so, how do you activate it?
Which Python version are you using?
Can you share your pip freeze?
What is the value of your system's PATH?

It is most probably an issue with your environment setup.

My recommendation for now, as a workaround, use Pipenv to run all your applications. :wink:
