Probelm running POC mode without GPU

[falibabaei]

Hi,
I have the following error when I try to start poc mod
nvflare poc --start -gpu 0
Failed to get host gpu ids:('Failed to call nvidia-smi with query index', '')
how can I disable the usage of GPU?

if you don't have gpu, you can simple use
nvflare poc --start

Sorry, but it still encourages the same error

 raise ConfigError("Config error in {}: {}".format(self.config_file_name, secure_format_exception(e))) nvflare.fuel.common.excepts.ConfigError: Config error in ['/tmp/nvflare/poc/example_project/prod_00/site-1/startup/../ae216c7a-ad56-4649-8ac2-7e740884d87f/app_site-1/config/config_fed_client.json']: Error processing ['/tmp/nvflare/poc/example_project/prod_00/site-1/startup/../ae216c7a-ad56-4649-8ac2-7e740884d87f/app_site-1/config/config_fed_client.json'] in JSON element {'name': 'PTFilePipeLauncherExecutor', 'args': {'launcher_id': 'launcher', 'heartbeat_timeout': 60}}: path: executors.#1.executor, exception: Cannot find component class "PTFilePipeLauncherExecutor"

may sure you are using the correct nvflare version.
assume you have done the git pull to get the latest dev branch. Can you find the class "PTFilePipeLauncherExecutor" in the source code ?

@YuanTingHsieh can you help ?

here is my nvflare version
nvflare --version
NVFlare version is 2.4.0.dev+30.gb2a46a61.dirty
But I can not find PTFilePipeLauncherExecutor

[chesterxgchen]

it should be here : https://github.com/NVIDIA/NVFlare/blob/dev/nvflare/app_opt/pt/file_pipe_launcher_executor.py

I changed the version and it worked. Thanks
