Question

我正在使用tensorflow 1.9进行自定义对象检测，并遵循与https://tensorflow-object-detection-api-tutorial.readthedocs.io/en/latest/training.html#preparing-workspace中相同的步骤。

但是在训练模型时，我遇到了错误。

(tensorflow_cpu) C:\Users\Z004032A\Documents\Tensorflow\workspace\training_demo>python train.py --logtostderr --train_dir=training/ --pipeline_config_path=training/ssd_inception_v2_coco.config

Instructions for updating:
Use object_detection/model_main.py.

在处理上述异常期间，发生了另一个异常：

任何人都可以帮助我如何解决该问题，并告诉我哪个tensorflow版本最适合自定义对象检测

Answer 1

这可能是Windows使用C：\作为默认用户目录引起的。当您以字符串形式在Python中使用此用户目录时，可能会出现unicode错误，因为使用了\ U unicode转义。

尝试复制反斜杠。换句话说，将C:\User\Documents变成C:\\User\\Documents。

关于哪种Tensorflow最佳版本，没有“最佳”版本。我建议使用与您正在使用的任何库相同的TF版本。我也建议不要在原始TF中编码。而是使用现有的库，例如YOLO。只需Google“最佳对象检测库tensorflow”，然后选择现有库之一。

我们自己对象的tensorflow对象检测
