你能修复我的代码来计算词汇丰富度吗?

Could you fix my code to compute lexical richness?

我正在尝试使用 LexicalRichness (https://pypi.org/project/lexicalrichness/)。我复制并粘贴了代码:

import lexicalrichness
from lexicalrichness import LexicalRichness

text = """Measure of textual lexical diversity, computed as the mean length of sequential words in
                a text that maintains a minimum threshold TTR score.

                Iterates over words until TTR scores falls below a threshold, then increase factor
                counter by 1 and start over. McCarthy and Jarvis (2010, pg. 385) recommends a factor
                threshold in the range of [0.660, 0.750].
                (McCarthy 2005, McCarthy and Jarvis 2010)"""

use_TextBlob=True
lex = lexicalrichness(text)

print(lex.words)
print(lex.terms)
print(lex.ttr)
print(lex.rttr)
print(lex.cttr)
print(lex.msttr(segment_window=25))
print(lex.mattr(window_size=25))
print(lex.mtld(threshold=0.72))
print(lex.hdd(draws=42))

但是不行(报错信息是:TypeError: 'module' object is not callable)

你能帮帮我吗?提前致谢!

检查此行是否大写:lex = LexicalRichness(text)
