Pip3 Hilang Ketergantungan?

Saya telah menginstal Ubuntu Gnome terbaru hari ini, dan sedang menyiapkan mesin saya untuk pekerjaan yang berhubungan dengan ilmu data. Ketika saya mencoba menginstal tensorflow-gpu, saya mengalami crash dari pip3:

[email protected]:~/Desktop$ pip3
Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/pip/_vendor/__init__.py", line 33, in vendored
    __import__(vendored_name, globals(), locals(), level=0)
ImportError: No module named 'pip._vendor.pkg_resources'

During handling of the above exception, another exception occurred:

Saya mencoba membersihkan python3-pip dan menginstal ulang, masih tidak berhasil. Saya mendapatkan yang di atas hanya dengan menjalankan pip3 di terminal dan tekan ENTER.

Ada ide?

EDIT:Juga dua jalur berbeda untuk pip dan pip3:

[email protected]:~$ which pip
/home/me/.local/bin/pip
[email protected]:~$ which pip3
/usr/bin/pip3

Jawaban yang Diterima:

Saya memperbaikinya dengan membuat lingkungan virtual baru

1. Lingkungan virtual baru dapat dibuat dengan:

   python3 -m venv /tmp/newvenv
   

2. Kemudian saya memeriksa apakah pip berfungsi dengan baik di lingkungan virtual baru:

   cd /tmp/newvenv/bin
   ./pip3
   

Ini memberi saya pesan normal seperti berikut:

Penggunaan:
pip [opsi]

Perintah:

instal Instal paket.

unduh Unduh paket.

…

Namun, pip3 masih gagal.

    pip3

Ini masih memberi saya pesan kesalahan.

Kemudian saya memutuskan untuk menyalin versi pip yang berfungsi ke direktori home. Untuk dua langkah di bawah ini (#3 dan #4) Anda mungkin ingin menyimpan salinan cadangan.

3. Saya telah menimpa pip dan pip-9.0.1.dist-info dari lingkungan virtual ke direktori home:

   cp -r /tmp/newvenv/lib/python3.5/site-packages/pip ~/.local/lib/python3.5/site-packages/
   cp -r /tmp/newvenv/lib/python3.5/site-packages/pip-9.0.1.dist-info ~/.local/lib/python3.5/site-packages/
   

4. Saya juga menyalin dua file berikut:

   cp /tmp/newvenv/lib/python3.5/site-packages/pkg_resources/__init__.py ~/.local/lib/python3.5/site-packages/pkg_resources/ 
   cp /tmp/newvenv/lib/python3.5/site-packages/pkg_resources/py31compat.py ~/.local/lib/python3.5/site-packages/pkg_resources/
   

Setelah langkah-langkah ini, pip3 berfungsi dengan baik dalam kasus saya.
