Error while running examples on README

I am trying to run GNES locally on my Linux machine. However, when I run bash run.sh, I received the following errors.

E:EncoderService:[bas:run:305]:could not determine a constructor for the tag '!GPT2Encoder'
in "gpt2.yml", line 3, column 5

Namely, there is something wrong with gpt2.yml. I replaced the value of model_path with a real path to a downloaded GPT2 model, but it still did not work.

I installed gnes and also was running the docker service. Is there anything else we need to do to get it working? Thanks!

Hi, thanks again ❤️ for trying GNES and giving feedback at the early stage. I'd like to introduce you the new GNES Flow API (available since v0.0.46), enables a pythonic and intuitive way for building workflow in GNES. As an example, an indexing workflow can be simply defined as:

flow = (Flow(check_version=False, ctrl_with_ipc=True)
        .add_preprocessor(name='prep', yaml_path='yaml/prep.yml', replicas=3)
        .add_encoder(yaml_path='yaml/incep.yml', replicas=6)
        .add_indexer(name='vec_idx', yaml_path='yaml/vec.yml')
        .add_indexer(name='doc_idx', yaml_path='yaml/doc.yml', recv_from='prep')
        .add_router(name='sync', yaml_path='BaseReduceRouter', num_part=2, recv_from=['vec_idx', 'doc_idx']))

# then use it for indexing
with flow(backend='process') as fl:
    fl.index(bytes_gen=read_flowers(), batch_size=64)

🔰 You can find some resources here to help you getting started quickly:

🙇 Give it a try and we welcome your feedback and contribution.

Hi @hanxiao , Thanks for this great contribution.

I was running the very initial sample (flower classification via query).
I did pip install only. I ran in terminal (not in jupyter-notebook).
I came up with this error,

>>> flow = (Flow(check_version=False)
...         .add_preprocessor(name='prep', yaml_path='yaml/prep.yml')
...         .add_encoder(yaml_path='yaml/incep.yml')
...         .add_indexer(name='vec_idx', yaml_path='yaml/vec.yml')
...         .add_indexer(name='doc_idx', yaml_path='yaml/doc.yml', recv_from='prep')
...         .add_router(name='sync', yaml_path='BaseReduceRouter', num_part=2, recv_from=['vec_idx', 'doc_idx']))
W:Flow:[__i:_po:173]:this object is not named ("name" is not found under "gnes_config" in YAML config), i will call it "Flow-e96c35ae". naming the object is important as it provides an unique identifier when serializing/deserializing this object.

Some sort of arg error in yml file? is it that i missed to install some packages? because i just install with pip installl gnes but not pip install gnes[all]

jageshmaharjan commented

opps, my bad. I was running under different repo, so it couldn't find the yml files under yaml directory.
Can ignore the my above comment
