pip install beberapa paket
Untuk pip install beberapa paket, pisahkan dengan spasi:
pip install scikit-learn statsmodels
Tingkatkan beberapa paket:
pip install --upgrade scikit-learn statsmodels
pip install dengan requirements.txt
Berkas requirements.txt berisi daftar paket yang akan dipasang:
cat requirements.txt
scikit-learn
statsmodel
Kebanyakan pengembang Python menyertakan requirements.txt di repo Github mereka.
pip install dengan requirements.txt
-r membuat pip install memasang paket dari berkas siap pakai:
-r, --requirement <file>
Install from the given requirements file. This option can be used multiple times.
Pada contoh kita:
pip install -r requirements.txt
setara dengan
pip install scikit-learn statsmodel
