【R329开发板评测】开发板实机测试vgg16

R329 AIPU 实机测试vgg16(失败)

先参考下面这个帖子装好Debian系统。

R329开发板教程之四|Debian系统初体验

先生成量化模型

aipubuild config/vgg_16_build.cfg

vgg_16_build.cfg文件内容如下:

[Common]
mode=build

[Parser]
model_name = vgg_16
detection_postprocess = 
model_domain = image_classification
output = vgg_16/fc8/squeezed
input_model = ./vgg_16_model/frozen.pb
input = input
input_shape = [1,224,224,3]

[AutoQuantizationTool]
model_name = vgg_16
quantize_method = SYMMETRIC
ops_per_channel = DepthwiseConv
calibration_data = ./preprocess_vgg_16_dataset/dataset.npy
calibration_label = ./preprocess_vgg_16_dataset/label.npy
preprocess_mode = normalize
quant_precision=int8
reverse_rgb = False
label_id_offset = 0

[GBuilder]
outputs=./aipu.bin
profile= True
target=Z1_0701

上传模型到sipeed MaixSensor板子

配网在上面那篇文章里已经有说明了,这里我们直接用ifconfig查看板子ip地址:

AIPU_alloc_tensor_buffers在申请内存时报错,猜测是不是vgg16模型太大了?

我现在去model zoo里面找个别的模型试试。

试试resnet50.

model zoo去GitHub下载,下载模型需要用FTP客户端。

按照上面的操作将模型上传到板子,执行结果如下:
