IndexingError:此编写器已关闭
写入程序应该在上下文范围内,因此我不确定它为什么会关闭,尽管它是新创建的。如何解决新索引上的索引错误?writer.commit()
保存更改并关闭写入程序
然后在语句末尾,以ix.writer()作为编写器:
尝试关闭已关闭但不存在的编写器
因此,您的with
语句相当于:
try:
writer = ix.writer()
writer.add_document(hashID=str(uuid.uuid4()))
writer.commit()
finally:
writer.commit()
作为一种解决方案,无论您是在with
语句中省略writer.commit()
,还是在每次要提交时使用语句摆脱并重新创建writer
