Google Colab - tensorflow 对象检测 api - 'function' 对象没有属性 'called'

Question

我尝试测试对象检测时遇到以下错误api model_builder_test.py。

!apt-get install -y -qq protobuf-compiler python-pil python-lxml
!git clone --quiet https://github.com/tensorflow/models.git

import os
os.chdir('models/research')

!protoc object_detection/protos/*.proto --python_out=.
import sys
sys.path.append('/content/models/research/slim')

%run object_detection/builders/model_builder_test.py

运行model_builder_test.py

后出现如下错误

.W0220 03:22:35.097244 140099951081344 deprecation.py:323] From /content/models/research/object_detection/anchor_generators/grid_anchor_generator.py:59: to_float (from tensorflow.python.ops.math_ops) is deprecated and will be removed in a future version.

AttributeError: 'function' object has no attribute 'called'

Answer 1

我就是这样解决这个问题的：

将 prompt-toolkit 安装到版本 1.0.15，如下面的 link 中所述 https://github.com/jupyter/jupyter_console/issues/158
重启运行激活包时间
使用'!python'代替'%运行'

Google Colab - tensorflow 对象检测 api - 'function' 对象没有属性 'called'

Google Colab - tensowflow object detection api - 'function' object has no attribute 'called'

matplotlib

python-3.x

tensorflow

object-detection-api

google-colaboratory
