устанавливаю пакет

 pip install pandas

 mport pip
installed_packages = pip.get_installed_distributions()
installed_packages_list = sorted(["%s==%s" % (i.key, i.version)
     for i in installed_packages])
print(installed_packages_list)

 import pandas as pd
pd.test()

 Traceback (most recent call last):
  File "/usr/lib64/python3.6/site-packages/pandas/util/_tester.py", line 12, in test
    import pytest

Traceback (most recent call last):

ModuleNotFoundError: No module named ‘pytest’

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File “pandas_test.py”, line 3, in <module>
pd.test()

raise ImportError(“Need pytest>=3.0 to run tests”)
ImportError: Need pytest>=3.0 to run tests

Спасибо Помогло!

Но теперь когда запускаю тест то получаю

или ещё что доставить надо?

Насколько я понял, это предупреждение о том что в дальнейших версиях эта функция будет недоступна. Но я могу ошибаться…
