Pengalaman saya sendiri dalam instalasi Python dan semua paket yang dibutuhkan. Diuji pada Ubuntu 18.04 (tidak diuji pada 17.10). Saya bisa saja salah, karena saya bukan spesialis di Ubuntu.
Lebih baik gunakan perintah apt
( apt-get
) daripada pip
perintah, karena:
- apt installs hanya diuji pada paket dan dependensi Ubuntu;
- sudo apt update / upgrade perintah membuat paket tetap terbaru;
- jika Anda ingin menginstal / memperbarui paket untuk semua pengguna di sistem Ubuntu Anda, tidak hanya untuk akun lokal Anda sendiri;
- jika Anda menginginkan paket untuk Ubuntu, maka sistem operasi dapat menggunakannya juga.
Untuk versi lain dari paket, seseorang harus menggunakan lingkungan virtual. Atau buat dan uji paket dari kode sumber (hanya untuk spesialis).
Jangan hapus python3 saat ini, jika tidak, OS Ubuntu akan rusak.
# Refreshing the repositories
sudo apt update
# Update software
sudo apt upgrade
# Install Python and necessary packages.
# Install pip for 2.7 and then python 2.7 itself
sudo apt install python-pip
sudo apt install python2.7
# Install pip for 3.6
sudo apt install python3-pip
# Install currently supported by Ubuntu python 3.x version.
sudo apt install python3
# Don't delete current python3, otherwise Ubuntu OS will BROKE.
# Better don't install the newest versions 3.7, 3.8, 4.0, etc. on the whole OS (globally).
# This command works, but it's a bad idea to use it -- sudo apt install python3.7
# in this case import of numpy (import numpy) and other modules will fail for python3.7,
# because 3.6 is the current (global) python version for Ubuntu, not 3.7.
# Use "sudo apt install python3" not "sudo apt install python3.7" command for python 3.x installation.
# If you need 3.7 or newer, use local virtual environment.
# It's a bad idea to have several versions of python 3.x globally at the same time.
# Use only currently supported by Ubuntu python 3.x version globally. At this moment it is 3.6.
# Install numpy, scipy, matplotlib, scikit-learn, scikit-image,
# opencv with contributions, pandas, pillow, psutil, spur, cython,
