私は rdflib バージョン 3.2.3 を使用していましたが、すべて正常に動作していました。4.0.1 にアップグレードした後、次のエラーが発生し始めました。
RDFa 解析エラー! 'ascii' コーデックは位置 5454 のバイト 0xc3 をデコードできません: 序数が範囲外です (128)
これを機能させるためにさまざまな方法を試しましたが、これまでのところ成功していません。以下は私の試みです。
いずれの場合も、私は：
from rdflib import Graph
最初の試み：
>>> lg =Graph()
>>> len(lg.parse('http://creativecommons.org/licenses/by/3.0/'))

3 回目の試行: エラーは発生しませんが、結果も得られません

だから誰かが私が間違っていることを教えてください！:)
