Nextflow脚本块导入Python模块q2_predict_dysbiosis失败求助

我的问题与Stack Overflow上两个同类问题情况一致，使用的是某仓库中的q2_predict_dysbiosis代码（该模块无安装说明，本地直接运行正常，但在Nextflow脚本中无法被找到）。

我的Nextflow代码 #

process q2_predict_dysbiosis { 
    publishDir 'results', mode: 'copy'

    input:
    path abundance_file
    path species_abundance_file
    path stratified_pathways_table
    path unstratified_pathways_table

    output:
    path "${abundance_file.baseName}_q2pd.tsv"

    script:
    """
    #!/usr/bin/env python

    from q2_predict_dysbiosis import calculate_index
    import pandas as pd

    pd.set_option('display.max_rows', None)

    taxa = pd.read_csv("${species_abundance_file}", sep="\\t", index_col=0)
    paths_strat = pd.read_csv("${stratified_pathways_table}", sep="\\t", index_col=0)
    paths_unstrat = pd.read_csv("${unstratified_pathways_table}", sep="\\t", index_col=0)

    score_df = calculate_index(taxa, paths_strat, paths_unstrat)
    score_df.to_csv("${abundance_file.baseName}_q2pd.tsv", sep="\\t", float_format="%.2f")
    """
}

错误信息 #

Caused by:
  Process `q2_predict_dysbiosis (1)` terminated with an error exit status (1)


Command executed:

  #!/usr/bin/env python

  from q2_predict_dysbiosis import calculate_index

  score_df = calculate_index(taxa, paths_strat, paths_unstrat)
  score_df.to_csv("abundance1_q2pd.tsv", sep="\t", float_format="%.2f")

Command exit status:

Command output:

Command error:
  Traceback (most recent call last):

已尝试的解决操作 #

• 在script.nf所在目录创建bin/目录，将q2_predict_dysbiosis.py放入其中，无效果
• 修改shebang声明，无效果

我已经参考Nextflow官方文档中依赖管理的说明操作，但问题仍未解决。希望保留当前的代码块形式，不单独运行外部script.py文件。
