如何使用bioinfokit创建火山图？

Question

我一直在尝试使用python和bioinfokit在excel文件中创建基因表达数据的火山图。我使用熊猫创建了一个数据帧，然后消除了一些负值。然后我尝试在最后一行代码中创建火山图

import pandas as pd
import numpy as np
import bioinfokit
from bioinfokit import analys, visuz


panda_brie = pd.read_csv("C:\\Users\\amorgan\\Documents\\brie_gRNA_stats.csv", encoding='ISO-8859-1', low_memory=False)
shape = panda_brie.shape
print(shape)
panda_brie = panda_brie.loc[(panda_brie[("fold_change")] > 0)]
shape = panda_brie.shape
print(shape)


bioinfokit.visuz.gene_exp.volcano(df=panda_brie, lfc="log_fold_change", pv="log_p_value")

我收到以下错误，不确定该怎么办
