paddlepaddle踩坑记（二）

可别手动编译paddlepaddle了！本蒟蒻才疏学浅，竟以为DLL load failed是64位系统的锅，没想到今天随便倒腾了一下给解决了。
我手动编译了一个星期，尝试了mingw，结果不支持bigobj，换VS，（本蒟蒻以前没有装它），600多个项目只成功了40多个，生成的setup.py也有问题，问题是：缺少mkldnn.dll。
让我不禁想到了DLL load failed，莫非它的问题就是在这里？
结果我把C:\Program Files\Python36\Lib\site-packages\paddle\libs\mkldnn.dll拷贝到C:\Program Files\Python36\Lib\site-packages\paddle\fluid目录下，就不再报dll load failed了！
其实这个DLL load failed指的不是core_avx.pyd，而是用于深度学习加速CPU的mkldnn.dll，真是…
可是第二个错来了，

Traceback (most recent call last):

肿么回事？打开C:\Users\Administrator.paddlehub\conf\config.json，里面竟然是空的！怎么办？喂点代码吃吃：
{"server_url": ["http://paddlepaddle.org.cn/paddlehub"], "resource_storage_server_url": "https://bj.bcebos.com/paddlehub-data/", "debug": false, "log_level": "DEBUG", "hub_name": "3c1171f799b87cc37db3f232159d2809-1587800357"}
完美解决！试了一下人脸识别：

import paddlehub as hub
module=hub.Module(name='pyramidbox_lite_mobile_mask')
image_list=['face.jpg']#图片名称
input_dict={'image':image_list}
module.face_detection(data=input_dict)

face.jpg识别后的结果：
希望对大家有所帮助！（本蒟蒻先溜了…
