为什么我已经安装了Tensorflow的所有库，却出现了无目录的错误？

Question

我是按照这个教程来做的。https:/github.comRomRocobjdet_train_tensorflow_colabblobmasterobjdet_custom_tf_colab.ipynb。

当我试图运行第一段代码时，我得到了这样的错误："我的代码是："。

!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

我得到了这个错误。

/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

我已经在Google Colab中安装了所有的库 就像教程上说的那样 所以我不明白为什么会出现这样的错误 也不知道该如何解决这个问题 任何帮助都将是非常感激的。

我能够在Google Colab中重新创建你的问题。

!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

输出。

[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

解决方案： 要解决这个问题，你可以改变你当前的目录。/content 到 /root/models/research 在运行你的代码之前，加入以下两行。

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

以下是更新后的代码

%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

产出：

/root
/root/models/research
