你好，麻烦问一下这个问题怎么解决啊 mxnet.base.MXNetError: [16:50:21] src/ndarray/ndarray.cc:1285: GPU is not enable

你好，麻烦问一下这个问题怎么解决啊 mxnet.base.MXNetError: [16:50:21] src/ndarray/ndarray.cc:1285: GPU is not enable

Download the correct version of mxnet by using "pip install mxnet-cu***" *** refers to your cuda version

[yuanhanxiagn]

Thank you

[yuanhanxiagn]

你好，再麻烦问一下这个问题怎么解决啊 OSError: libcudart.so.10.0: cannot open shared object file: No such file or directory

[yuanhanxiagn]

麻烦问一下你用的是什么版本的mxnet、gluoncv?我安装的版本好像不太对，老是报错，哈哈

[njvisionpower]

Hi,

我用的mxnet1.5.0，gluoncv0.5.0。看你的报错显然是CUDA相关错误，比如CUDA是否安装正确、环境变量是否正确、所用CUDNN是否匹配等等，具体内容可以自己Google/Baidu下哈。

我的gluoncv是0.5.0但还是报各种各样的错，害。。作者是用的mxnet=1.5.0 gluoncv是0.5.0 可我还是运行不起来

@yuanhanxiagn @liuwen-nj 有安装问题的话可以参考官方链接

[liuwen-nj]

@njvisionpower 执行python test_symbol.py 时出现： apache-mxnet-src-1.5.0-incubating/python/mxnet/gluon/block.py:1159: UserWarning: Cannot decide type for the following arguments. Consider providing them as input: data: None input_sym_arg_type = in_param.infer_type()[0] [16:05:27] src/operator/nn/./cudnn/./cudnn_algoreg-inl.h:97: Running performance tests to find the best convolution algorithm, this can take a while...

[njvisionpower]

这个打印无所谓，最终能执行输出结果就行，那个环境变量是挑选卷积的，不想用的话置0就可以了。

[liuwen-nj]

@njvisionpower 提示这个错误，是不是安装环境的问题？

[liuwen-nj]

@njvisionpower 我关闭 CUDNN 就可以了。

[Single430]

将老哥的数据集放在ssd-tensorflow 上跑，效果极差，不知道 @njvisionpower 有什么想法没，运行1w step了，map只有0.25

[njvisionpower]

@Single430 你跑的1w个step batch size用的多大，还有就是输入大小和网络用的什么？我用gluoncv的SSD resnet 512也train过，map虽然没有YOLOv3高，但也低不了几个点。

[Single430]

BS 32， 输入300x300，vgg16预训练模型 @njvisionpower

[Single430]

使用了您的模型，用测试算了mAP 效果没有达到0.88，用的是facebook提供的voc_eval.py来计算的, 是有什么其它因素吗？ @njvisionpower network = "yolo3_darknet53_voc" hat: P 0.97 R 0.4 AP 0.76 person: P 0.97 R 0.4 AP 0.76

---

mAP : 0.76 < 0.88

[njvisionpower]

@Single430 R太低了，我用gluoncv自带的map计算方法，训练的时候二者至少八十几

[liuwen-nj]

@njvisionpower 请问有没有caffe模型？谢谢

[VectXmy]

@Single430 看训练代码作者用的是voc07metric，voc_eval.py应该用的是voc10的标准，两个AP计算方式有不同，但是R这么低应该是有问题的

[Single430]

我这个是在test.txt文件上测的，voc_eval.py是官方提供的，而且里面可以选择用voc07标准，不过可能是我什么地方不对吧，请问你是怎么算的？ @VectXmy

Hello , tel me please how can be change the color of detection , i doesn't find the line must be edited to chose the color ; like you see in images , the person who wearing hat must be draw with green color and the person who doesn't wearing hat must be draw with red color
