pip install rwslib

Common errors

error ModuleNotFoundError: No module named 'rwslib.builders' ↓

cause rwslib 1.2.0+ refactored builders into a subpackage; older code using `from rwslib.builders import *` fails if package missing.

fix

Upgrade to rwslib >=1.2.0 or check installation with pip install --upgrade rwslib.

error AttributeError: module 'rwslib' has no attribute 'RWSCommand' ↓

cause RWSCommand is not imported at top-level; it resides in `rwslib.rws_cmd`.

fix

Use from rwslib.rws_cmd import RWSCommand instead.

Warnings

breaking Python 3.6 support dropped after version 1.2.2; requires Python >=3.8 as of 1.2.12+. ↓

fix Upgrade to Python 3.8 or newer.

deprecated The enum34 backport is no longer needed for Python 3.4+; installation is conditional but may cause conflicts if pinned. ↓

fix Use rwslib 1.2.2+ which conditionally installs enum34 only for Python <3.4.

gotcha RWSCmd module (rws_cmd) is not a standalone executable; it must be invoked via the Python client. ↓

fix Use `from rwslib.rws_cmd import RWSCommand` and call methods, not as a script.

Quickstart

Initialize RWS client and fetch a dataset. Replace url, username, password, apikey, study_oid, and environment as needed.

from rwslib import RWS

rws = RWS(url='https://your-instance.imedidata.com', username='user', password='pass', apikey='key')
response = rws.get_datasets(dataset='SUBJECT', study_oid='STUDY1', study_env='Prod')
print(response)
