Unable to establish a connection with Milvus without relevant useful information.

[Kinkisong]

Milvus has been installed via Docker, but I am unable to connect to it using ann-benchmark, and there is no useful error message provided.

Milvus is benchmarked using a standalone, non-client/server version (https://github.com/zilliztech/Knowhere). You would have to write a wrapper yourself if you want to test their official release.

Sorry, this was outdated. It seems that @cococo2000 added a lot of new functionality to milvus, and it connects to the db. It should be run using --algorithm milvus as far as I can see.

The names of the latest algorithms in milvus can be found in the ann_benchmarks/algorithms/milvus/config.yml file, including milvus-flat, milvus-ivfflat, milvus-hnsw, milvus-scann, milvus-ivfpq, and milvus-ivfsq8.

To run a command using one of these algorithms, you could use:

python run.py --algorithm milvus-flat  --runs 1  --dataset mnist-784-euclidean

Thanks @cococo2000. Is there any reason to not have them tested in github actions? They don't seem to appear in

The Docker tag for all these algorithms is ann-benchmarks-milvus, which is why the library includes only the milvus parameter. Additionally, with --max-n-algorithms 3, the GitHub Action will run tests on three of these algorithms.

@cococo2000 I still cannot connect to milvus with new command. Is here any wrong with my command? Thanks for your help!

It seems that the Docker image ann-benchmarks-milvus was not built using python install.py ..... before running the benchmark. Running the following command should resolve the issue:

python install.py --algorithm milvus

@GreateFang Let me know if you need any further adjustments!

Hi coco @cococo2000 ,I have used your image and it works!Thanks a lot again! Could you help to check If this output is normal? It have stopped outputting for a while. should I just wait for result? And how long will it usually take( I use angular-25 dataset)?

Sorry for keeping bothering, Thanks a lot for your patiently reply.

@GreateFang It appears that something is not functioning correctly. The program is unable to connect to the Milvus server properly, likely due to a pthread_create failed: Operation not permitted error. I did not encounter this issue when testing on Ubuntu, so I suspect the problem might be related to using the CentOS system. Additionally, for the Operation not permitted error, you might want to try running the program as root.

@GreateFang You can see the normal milvus test output here

I have solved this problem with upgrading docker version and docker-compose version. Now it works perfectly, thank you for your help! @cococo2000
