Question

无论我使用object_detection/legacy/eval.py脚本还是object_detection/model_main.py，无论何时开始评估，我都存在细分错误。我试图重新安装tensorflow，protobuf编译器并重新安装tensorflow / modules对象检测api的所有依赖项，但没有帮助。我正在使用python 3。

Tensorflow版本：1.15.0

我给eval.py打电话的方式：

python object_detection/legacy/eval.py \
    --logtostderr \
    --eval_dir=${TRAIN_DIR} \
    --checkpoint_dir=${TRAIN_DIR} \
    --pipeline_config_path=${PIPELINE_CONFIG_PATH}

这是运行脚本时的日志段

Answer 1

即使在注释部分中也提供了解决方案（答案部分），还是为了社区的利益。

由于模型中涉及的计算非常占用内存，因此在GPU（而不是CPU）中执行模型可以解决该错误。
