A golang-based data loader which can be used from Python. Compatible with a soon-to-be open sourced VectorDB-enabled data stack, which exposes HTTP requests.
Datago handles, outside of the Python GIL
- per sample IO from object storage
- deserialization (jpg and png decompression)
- some optional vision processing (aligning different image payloads)
- optional serialization
Samples are exposed in the Python scope as python native objects, using PIL and Numpy base types. Speed will be network dependent, but GB/s is typical.
Datago is rank and world-size aware, in which case the samples are dispatched depending on the samples hash.
Use it
from datago import datago
config = datago.GetDefaultConfig()
# Check out the config fields, plenty of option to specify your DB query and optimize performance
client = datago.GetClient(config)
client.Start() # This can be done early for convenience, not mandatory (can fetch samples while models are instanciated for intance)
for _ in range(10):
sample = client.GetSample() # This start the client if not previously done, in that case latency for the first sample is higherPlease note that the image buffers will be passed around as raw pointers, they can be re-interpreted in python with the attached helpers
See helper functions provided in polyglot.py, should be self explanatory
Build it
$ sudo apt install golang libjpeg-turbo8-dev libvips-dev
$ sudo ldconfigFrom the root of this project:
$ go build cmd/main/main.goRunning it:
$ ./main --help` will tell you all about itRunning it with additional sanity checks
$ go run -race cmd/main/main.goFrom the root folder
$ go test -v tests/client_test.go- Install the dependencies as detailed in the next point
- Run the
generate_python_package.shscript
$ python3 -m pip install pybindgen
$ go install golang.org/x/tools/cmd/goimports@latest
$ go install github.com/go-python/gopy@latest
$ go install golang.org/x/image/drawNOTE:
- you may need to add
~/go/binto your PATH so that gopy is found. -
- Either
export PATH=$PATH:~/go/binor add it to your .bashrc
- Either
- you may need this to make sure that LDD looks at the current folder
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:.
then from the /pkg folder:
$ gopy pkg -author="Photoroom" -email="team@photoroom.com" -url="" -name="datago" -version="0.0.1" .then you can pip install -e . from here.
python3 setup.py sdist
python3 -m twine upload dist/* --verbose
