【问题描述】:
当我尝试使用来自 github https://github.com/tensorflow/models/tree/master/research 的 tensorflow/models 训练 object_detection 网络时,我收到以下错误:
Traceback (most recent call last):

我使用 models/research/object_detection 中的以下命令开始训练
python train.py --logtostderr --model_config_path=./my_tests/faster_rcnn.config --train_dir=./train
- 我使用的是 tensorflow 1.4.1(我无法升级到 1.5,因为管理员由于某些原因无法安装 CUDA 9 版本)
- 我用 Python 2.7 和 Python 3.5.2 都试过了
- Ubuntu 16.04
- Faster-RCNN 和 SSD 存在相同问题
我的 .config 文件如下所示
# Faster R-CNN with Inception v2, configuration for MSCOCO Dataset.
# Users should configure the fine_tune_checkpoint field in the train config as
# well as the label_map_path and input_path fields in the train_input_reader and
# eval_input_reader. Search for "PATH_TO_BE_CONFIGURED" to find the fields that
# should be configured.

你有什么想法吗?
