Question

背景：

Windows 10
Tensorflow：1.12

遵循官方文件here。由于数据集是根据实验生成的，因此可用的图像很少，大约有50个训练图像和10个测试图像。预先训练的模型是 ssd_inception_v2_coco 。使用

进行训练时

python train.py --logtostderr --train_dir=training/ --pipeline_config_path=training/ssd_inception_v2_coco.config

看到以下输出，程序退出。

我猜模型没有得到训练，因为张量板看起来像这样：

好吧，您知道如何开始培训吗？

Answer 1

尝试将--num_train_steps=10添加到您的cmd。

Answer 2

好吧，将图像调整为600 * 300后，一切正常。

训练object_detection不训练
