【问题描述】：

我刚刚开始使用 Python，虽然我知道一点 R。我想复制一些人已经做过的事情。我在 Jupyter 上的一个内核上收到此错误，我不立即知道该怎么做。有没有人对此有任何意见或经验？

Traceback (most recent call last):

    from param import ranked_blast_output_schema, blast_outfmt6_schema

由于错误是关于一些ranked_blast_output_schema，如果没有更多上下文，将很难为您提供更多帮助。

啊，好吧。我正在复制一个 Jupyter 笔记本，有人告诉我在 bash 上运行此链接。

lca_analysis.py --blast_type nt --fpath s3://org_name/contigs/CMS001_002_Ra_S1/blast_nt.m9 --filtered_blast_path s3://bucket_name/contig_quality/CMS001_002_Ra_S1/blast_nt_filtered.m9 --excluded_contigs_path s3://bucket_name/contig_quality/CMS001_002_Ra_S1/exclude_contigs_nt.txt --outpath s3://bucket_name/contig_quality/CMS001_002_Ra_S1/lca_nt.m9 --read_count_path s3://bucket_name/contigs/CMS001_002_Ra_S1/contig_stats.json --verbose True

然后，我遇到了这个错误

我刚刚使用 pip install param 来获取参数，安装很顺利。
