"tensorflow.python.framework.errors_impl.FailedPreconditionError" 而 运行 "model_main_tf2.py" 用于在 tensorflow 中训练目标检测模型
"tensorflow.python.framework.errors_impl.FailedPreconditionError" while running "model_main_tf2.py" for training object detection model in tensorflow
很多人也遇到过这个问题，但似乎总是因为命令行参数中的一些错误而发生
这是我的命令 运行
!python "/content/drive/My Drive/Tensorflow/models/research/object_detection/model_main_tf2.py" --model_dir="/content/drive/My Drive/Tensorflow/ssd_mobilenet_v2_fpnlite_320x320_coco17_tpu-8" --pipeline_config_path="/content/drive/My Drive/Tensorflow/ssd_mobilenet_v2_fpnlite_320x320_coco17_tpu-8/pipeline.config"
好像没有什么错误。
这是堆栈跟踪

错误来自 _pywrap_file_io.RenameFile()，其中 _pywrap_file_io 是从 tensorflow.python 导入的。我试图查看源代码以查找问题，但我找不到任何地方。
问题是否已经出现，因为我在 colab 运行 上？
张量流版本：2.3
Python版本：3.6
有人可以帮我解决这个问题吗？
问题是程序试图创建一个名为“checkpoint”的文件，但下载的模型中有一个同名文件夹。
有两种方法可以解决这个问题，
- 创建一个新文件夹并将其路径设置为 --model_dir
的参数
- 检查是否有名为'checkpoint'的文件夹，如果有，则更改文件夹名称。就我而言，我将其更改为“checkpoint0”。
