Value Error: buffer source array is read-only

[KMayank29]

I have attached the code snippet and the error I am having. Could you help me why spacy model is throwing the error when sent as ray remote task/actor?
Thanks

Please share code or terminal output as text, not as screenshots.

I'm not familiar enough with ray to say exactly what's going on, but some searching suggests this is an issue with differences in how Cython and ray handle memory. We haven't updated it in a while and it was designed to be used in a different way, but spacy-ray might be a helpful reference for you.

Thanks for the response @polm
When I run the same code on GPU using en_core_web_trf there is no error but as soon as I use cnn based models (md,lg) it throws error buffer source array is read-only.
The entite traceback:
output = model.ops.gather_add(vectors, keys) File "thinc/backends/numpy_ops.pyx", line 440, in thinc.backends.numpy_ops.NumpyOps.gather_add File "stringsource", line 660, in View.MemoryView.memoryview_cwrapper File "stringsource", line 350, in View.MemoryView.memoryview.__cinit__ ValueError: buffer source array is read-only

Sorry, but as I mentioned, we don't have enough familiarity with Ray to help you with this. It doesn't seem to be an issue with spaCy specifically, but rather something to do with memory management in Cython. I think you would have more luck asking for help through one of the official Ray channels.

If you do figure out what the issue is and there's something we can do in spaCy to improve it, we'd be glad to integrate a fix.
