Known Issues

Bugs

• The ZeroMQConnector will raise a _pickle.UnpicklingError: pickle data was truncated error if the serialized data is larger than the chunk size (64 MiB by default).
  • Affected versions: ==0.4.1
  • Fixed in 0.5.0 by PR #219.

Compatibility

• ProxyStore Endpoints are not supported for Python 3.7 on ARM-based Macs because aiortc does not have the corresponding wheels. The base ProxyStore package can still be installed on this software/hardware configurations---just not with the endpoints extras.
  • Affected versions: >=0.4.0,<0.6.0
  • Python 3.7 support will be removed in 0.6.0. See Issue #236.
• Newer versions of UCX-Py no longer support Python 3.7.
  • We test against and recommend using UCX-Py 0.30.00.
  • Affected versions: >=0.4.0,<0.6.0
  • Python 3.7 support will be removed in 0.6.0. See Issue #236.

MyPy

Implicit re-exports

Affected versions: <=0.5.1

Examples throughout the documentation generally suggest importing Store like the following.

example.py

from proxystore.store import Store

MyPy will raise an attribute defined error if run with --no-implicit-reexport.

$ mypy example.py --no-implicit-reexport
example.py:1: error: Module "proxystore.store" does not explicitly export attribute "Store"  [attr-defined]

This can be fixed by using the explicit import.

from proxystore.store.base import Store
