tensorflow - 谷歌 colab 上的 PYTHONPATH 问题

问题描述

从不同的论坛和教程看来，该命令 !python object_detection/builders/model_builder_test.py应该给出如下输出：

但就我而言，它并没有抛出任何输出。正常吗？这是我的全部代码和输出：

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

!apt-get install -qq protobuf-compiler python-pil python-lxml python-tk

!pip install -q Cython contextlib2 pillow lxml matplotlib

!pip install -q pycocotools

%cd /content/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


/content
fatal: destination path 'models' already exists and is not an empty directory.
