1. 问题描述

LZ使用xlrd读取file.xlsx的文档时，运行程序报错

Traceback (most recent call last):
  File "<input>", line 1, in <module>
  File "/root/.pycharm_helpers/pydev/_pydev_bundle/pydev_umd.py", line 197, in runfile
    pydev_imports.execfile(filename, global_vars, local_vars)  # execute the script
  File "/root/.pycharm_helpers/pydev/_pydev_imps/_pydev_execfile.py", line 18, in execfile
    exec(compile(contents+"\n", file, 'exec'), glob, loc)
  File "/home/fanrongrong/sentence-transformers/examples/transformers_tour/test_data/xlsx2txt.py", line 3, in <module>
    workbook = xlrd.open_workbook('./jqsj.xlsx')
  File "/root/anaconda2/envs/SentenceTrans3.9/lib/python3.9/site-packages/xlrd/__init__.py", line 170, in open_workbook
    raise XLRDError(FILE_FORMAT_DESCRIPTIONS[file_format]+'; not supported')
xlrd.biffh.XLRDError: Excel xlsx file; not supported

2. 解决方案

就离谱，居然不支持xlsx格式，最终在各种百度之下，找到了解决方案，居然是降版本！

conda install  xlrd==1.2.0

最后运行程序，问题解决，这个版本更新的意义是？
