训练过程中，BBOX Map忽然提高，但却不检测了。

[zhihonglujon]

问题类型：模型训练
问题描述
用裁剪训练的时候，BBox mAP忽然提高。但用模型验证检测图片，却全部的不检测了。

用Paddlex GUI 图像训练，裁剪训练的时候，BBox mAP忽然提高。但用模型验证检测图片，却全部的不检测了。不知道可能是什么原因？

1. 选择其它保存的epoch可以预测出框吗
2. 针对忽然map上涨的epoch，试着将预测时的阈值调低看下，是否会有预测框

[zhihonglujon]

预测时的阈值调低可以有预测框了，其他epoch阈值调低也可以有预测框。谢谢！

另外，还有两个问题：
1、有2000张的标注数据，精度只有0.3. 怎么提高精度呢？

2、模型压缩后，模型还是有175M。对端设备还是太大，能指定到20M以内吗？如何操作呢？谢谢！

另外，由于执行了多任务导致死机。异常重启后，无法启动PaddleX 怎么处理呢？谢谢！

如果你是通过PaddleLite部署，那可以在发布模型时，选择模型量化，发布到移动端，这样模型体积会有较明显的压缩。

查看下你的~/.paddlex/logs/paddlex.log 看看错误提示

[zhihonglujon]

好的 谢谢！2000张不同类型的标注图片，精度还是太低，精度怎么提高呢？有什么好方法吗？把标注图片搞到5000-10000张，Paddlex对精度提高有什么建议吗？谢谢！

[zhihonglujon]

异常重启后，不能启动Paddlex log信息。怎么处理呢？谢谢！

检查下有没有残留的paddlex进程，有的话清理后重试。
如果不行，可能是工作区中文件有异常，尝试将/home/zzj/.paddlex/paddlex.cfg配置文件删除后重试。

[zhihonglujon]

[zhihonglujon]

删除/home/zzj/.paddlex/paddlex.cfg 文件，还是不能启动Paddlex

[lailuboy]

看错误提示是已经有进程在运行，可能是残留进程存在。
ps -ef|grep paddlex 看下有没有其他进程存在，有的话先清理后重试。
