我试着关注 https://tensorflow-object-detection-api-tutorial.readthedocs.io/en/latest/training.html#training-the-model 在Google CoLab

一切顺利，构建了pycoTools，使用OBJECT_DETACTION/Packages/tf2/setup.py进行设置，使用object_detection/builders/model_builder_tf2_test.py，Create tfRecord进行测试，一切运行顺利，没有任何问题

但当培训开始时，总是失败

我一直在尝试使用较低版本的TensorFlow，如2.4.0，但问题仍然存在

推荐答案

我正在处理同样的问题，您需要在此处检查版本： https://www.tensorflow.org/install/source#gpu TensorFlow对象检测使用TensorFlow 2.6.0，因此您需要将cuDNN设置为8.1，而Colab运行时使用8.0.5。 我在这里解决了这个问题： https://developer.nvidia.com/cudnn 已注册并已下载

cudnn-11.2-linux-x64-v8.1.0.77.tgz

!tar -zvxf /content/drive/MyDrive/task/cudnn-11.2-linux-x64-v8.1.0.77.tgz

及更高版本

%%bash
cd cuda/include
sudo cp *.h /usr/local/cuda/include/

这解决了我的问题。
