Я настроил виртуальную среду с Python 3.9.2 и pip 21.0.1 и установил matplotlib(3.4.1). Но при импорте библиотеки

 import matplotlib.pyplot as plt
 

Возникает ошибка-

     Traceback (most recent call last):
  File "G:MachineLearningtut3.py", line 1, in <module>
    import matplotlib.pyplot as plt

Я попытался понизить рейтинг matplotlib и numpy, но та же ошибка продолжает появляться. Это пакеты, установленные в виртуальной среде —

 cycler==0.10.0
kiwisolver==1.3.1
matplotlib==3.4.1
numpy==1.18.5
pandas==1.2.4
Pillow==8.2.0
pyparsing==2.4.7
python-dateutil==2.8.1
pytz==2021.1
six==1.15.0
 

Может ли кто-нибудь помочь мне в этом вопросе?
