required: gpupaddle.set_device("gpu")
tensor = paddle.randn([512, 512, 512], "float") del tensorpaddle.device.cuda.empty_cache()
是遇到报错了么？运行的什么命令呢？
empty_cache只是释放不用的显存空间，一般不需要手动调用

就是在生成完一张图片时，我就用paddleocr.py识别图片的结果，报错如下，不知道有没有可以避免这种错误的识别方法

试一下这个呢？

paddle版本、cuda、cudnn版本是多少呢？
paddleocr2.7.5, cuda 10
paddlepaddle-gpu版本是多少？新版的paddle已经不支持cuda10了
2.3.2
cuda10.2好像还可以训练
paddle2.3.2是支持cuda10.2的，但是2.3.2是很老的版本了，目前最新已经是2.6.1了。我查了一下，最新的支持10.2的paddle是这个，可以重新安装一下试试：https://paddle-wheel.bj.bcebos.com/2.5.2/linux/linux-gpu-cuda10.2-cudnn7-mkl-gcc8.2-avx/paddlepaddle_gpu-2.5.2.post102-cp38-cp38-linux_x86_64.whl
我是win10
对准确率没有影响；得先解决报错的问题才行。
现在就是怀疑是因为paddle版本导致的显存未正常释放，所以想换一下paddle版本试试。
我先安装试试。
resnet34 和 svtr准确率哪个高？好像svtr训练速度特别慢
装了 2.5.2，直接报错了，。
File "C:\F\pycharm2020.2\PaddleOCR-2.7.5\ppocr\data\simple_dataset.py", line 36, in
继续用2.3.2，开始可以识别的。以下是部分结果，剔除0.15以下，0.95以上的

过了一段时间，就报错了
几个方案可以尝试：
这个 export在哪里加？windows也有效？
export 是设置环境变量的命令，windows用set
