Tensorflow 在colab中设置DeepLabV3

所以我想在colab建立deeplab

我正在跑步：

[1]

[2]

[3]

但是，最后一个命令返回

sh: 1: export: Drive/deeplab_files/slim:/content/drive/My Drive/deeplab_files/:/content/drive/My Drive/deeplab_files/slim: bad variable name
Traceback (most recent call last):
  File "deeplab/vis.py", line 28, in <module>
    from deeplab import common
ModuleNotFoundError: No module named 'deeplab'

从笔记本电脑成功导入的是Github回购协议，其中包含运行deeplab的Colab笔记本电脑。
我没有对它进行测试，但您将整个目录上载到Google Drive的方式不是在Colab上运行东西的正确方式。

---

将Colab视为一台单独的机器，您将在这台机器上安装您的Google驱动器。谷歌硬盘上的任何可用内容都不一定适用于Colab机器。您必须使用

sys.path.insert（0，）

将Google Drive文件夹的路径（例如

'\content\Drive\My Drive\'

）添加到Colab机器的

sys.path

，以使该路径可用于Colab机器上运行的python环境

解决了机器翻译问题。不幸的是，abggcv提供的关联回购遇到了这个问题所引用的同一个问题

您应该将回购克隆为正常，并正常运行所有内容。唯一的变化是，在运行train.py、eval.py或vis.py之前，需要运行以下块：

%cd /root/deeplabvc/models/research/
import sys
sys.path.extend(['/root/deeplabvc/models/research/', '/root/deeplab/models/research/slim/'])

请注意，

/root/deeplab/

是我克隆repo的路径。如果克隆repo的目录不同，则需要更改此选项

此外，由于某些原因，您将无法依次运行train.py/eval.py/vis.py。即使清除标志，也会出现关于重复标志的错误。要修复此问题，只需重新启动运行时（不会丢失文件）

分割快乐

Deeplab导入错误主要发生在未正确设置

PYTHONPATH

时。给出的安装说明不适用于COLAB环境。以下几点对我有用

%cd /content/deeplab/models/research/
!mkdir -p deeplab/datasets/pascal_voc_seg/exp/train_on_train_set/train
!mkdir -p deeplab/datasets/pascal_voc_seg/exp/train_on_train_set/eval
!mkdir -p deeplab/datasets/pascal_voc_seg/exp/train_on_train_set/vis
!echo ${PYTHONPATH}
%env PATH_TO_TRAIN_DIR=/content/deeplab/models/research/deeplab/datasets/pascal_voc_seg/exp/train_on_train_set/train
%env PATH_TO_DATASET=/content/deeplab/models/research/deeplab/datasets/pascal_voc_seg/tfrecord
%env PYTHONPATH=/content/deeplab/models/research:/content/deeplab/models/research/deeplab:/content/deeplab/models/research/slim:/env/python
!echo ${PYTHONPATH}

是我的COLAB笔记本，用于deeplab的培训，有效吗
