5img = cv2.imread("test.jpg")
6
7plt.imshow(cv2.cvtColor(img, cv2.COLOR_BGR2RGB))
8plt.show()

追記（半分解決しました）

ModuleNotFoundError: No module named 'apt_pkg'
は、
cd /usr/lib/python3/dist-packages
sudo cp apt_pkg.cpython-35m-x86_64-linux-gnu.so apt_pkg.so
を実行することで解決しました.

ImportError: cannot import name '_imaging' from 'PIL' (/usr/lib/python3/dist-packages/PIL/init.py)
の方の解決策がわからないのでご教授お願いします

自己解決

１つめのエラー
ModuleNotFoundError: No module named 'apt_pkg'
は、
cd /usr/lib/python3/dist-packages
sudo cp apt_pkg.cpython-35m-x86_64-linux-gnu.so apt_pkg.so
を実行することで解決しました.

２つめのエラー
ImportError: cannot import name '_imaging' from 'PIL' (/usr/lib/python3/dist-packages/PIL/init.py)
は、
/usr/lib/python3/dist-packages
の中にあるPIL/
を削除することで解決しました
