model_analyzer container gets Connection refused (111)

[ElsayedMMohammed]

Hi. I have built and run a model-analyzer image using the "Specific Version with Local Launch Mode" way (described here) as follows:

• git clone https://github.com/triton-inference-server/model_analyzer.git -b r24.11
• cd ./model_analyzer
• docker build --pull -t model-analyzer .
• docker run -it --gpus all -v /var/run/docker.sock:/var/run/docker.sock -v /home/qrf/workarea/elsayed/model_repository:/workspace/model_repo -v /home/qrf/workarea/elsayed/triton_outputs:/workspace/triton_outputs --net=host model-analyzer

The building ran smoothly without any errors. Then, I tried to run model-analyzer using the following command inside the container:

model-analyzer profile -f config.yaml

where config.yaml is:

# Path to the Triton Model Repository
model_repository: /workspace/model_repo

# List of the model names to be profiled <comma-delimited-string-list>
profile_models:
 fingerprinting:
   model_config_parameters:
     dynamic_batching:
       max_queue_delay_microseconds: [100, 200, 300]
   parameters:
     concurrency:
       start: 2
       stop: 10
       step: 4
     batch_sizes:
       start: 1
       stop: 10
       step: 2


# ALL THE FOLLOWING FIELDS ARE OPTIONAL 
# The directory to which the model analyzer will save model config variants
output_model_repository_path: ./results

# Allow model analyzer to overwrite contents of the output model repository
override_output_model_repository: true

# Export path to be used
export_path: ./profile_results

# Specifies the maximum number of retries for any retry attempt (default: 50)
client_max_retries: 5

# The protocol used to communicate with the Triton Inference Server. Only 'http' and 'grpc' are allowed for the values (default: grpc)
client_protocol: grpc

triton_launch_mode: docker

Then, I am getting the following error:

Have you tried running the quick-start (from the MA documentation) to confirm that your system can run a tritonserver for a basic case? When running in docker mode you also need to ensure that any paths (-v) passed in when issuing the docker run command are identical otherwise the tritonserver cannot find them.
