問題描述

為什麼當我安裝了 Tensorflow 的所有庫後，會出現無目錄錯誤？ (Why do I get a no directory error, when I have installed all the libraries for Tensorflow?)

我正在關注本教程：https://github.com/RomRoc /objdet_train_tensorflow_colab/blob/master/objdet_custom_tf_colab.ipynb

當我嘗試運行第一個代碼塊時：

!apt‑get install ‑qq protobuf‑compiler python‑tk

!pip install ‑q Cython contextlib2 pillow lxml matplotlib PyDrive

!pip install ‑q pycocotools

%cd ~/models/research
!protoc object_detection/protos/*.proto ‑‑python_out=.

import os
os.environ['PYTHONPATH'] += ':/content/models/research/:/content/models/research/slim/'

!python object_detection/builders/model_builder_test.py

我收到此錯誤：

/content
object_detection/protos/*.proto: No such file or directory
python3: can't open file 'object_detection/builders/model_builder_test.py': [Errno 2] No such file or directory

正如教程所說，我已經在 Google Colab 中安裝了所有庫，所以我不明白為什麼會出現此錯誤或如何修復它。任何幫助將不勝感激。

參考解法

方法 1:

I am able to recreate your issue in Google Colab

!apt‑get install ‑qq protobuf‑compiler python‑tk

!pip install ‑q Cython contextlib2 pillow lxml matplotlib PyDrive

!pip install ‑q pycocotools

%cd ~/models/research
!protoc object_detection/protos/*.proto ‑‑python_out=.

import os
os.environ['PYTHONPATH'] += ':/content/models/research/:/content/models/research/slim/'

!python object_detection/builders/model_builder_test.py

Output:

[Errno 2] No such file or directory: '/root/models/research'
/content
object_detection/protos/*.proto: No such file or directory
python3: can't open file 'object_detection/builders/model_builder_test.py': [Errno 2] No such file or directory

Solution: To fix this issue, you can change your current directory /content to /root/models/research by including below two lines before running your code.

%cd
!git clone ‑‑quiet https://github.com/tensorflow/models.git

Here is the updated code

%cd

!git clone ‑‑quiet https://github.com/tensorflow/models.git

!apt‑get install ‑qq protobuf‑compiler python‑tk

!pip install ‑q Cython contextlib2 pillow lxml matplotlib PyDrive

!pip install ‑q pycocotools

%cd ~/models/research
!protoc object_detection/protos/*.proto ‑‑python_out=.

import os
os.environ['PYTHONPATH'] += ':/content/models/research/:/content/models/research/slim/'

!python object_detection/builders/model_builder_test.py

Output:

/root
/root/models/research
