Caffe到Caffe2的转换

Question

我正在尝试对caffe2的模型运行预测，使用caffe2中包含的脚本从caffe转换。脚本正确地结束了，给出了"init_net.pb“和"predict_net.pb”。

当我尝试调用Predictor方法run()时，我得到以下错误消息：

Traceback (most recent call last):
  File "caffe2Inference.py", line 23, in <module>
    results = p.run(input)
RuntimeError: [enforce fail at conv_op_impl.h:21] X.ndim() == filter.ndim(). 3 vs 4 Error from operator: 
input: "data" input: "conv1/time_w" input: "conv1/time_b" output: "conv1/time" type: "Conv" arg { name: "stride" i: 1 } arg { name: "pad" i: 0 } arg { name: "kernel_h" i: 7 } arg { name: "kernel_w" i: 1 }

下面是我用来执行推理的代码：

# load up the caffe2 workspace
from caffe2.python import workspace, core
import numpy as np

# helper image processing functions
#import caffe2.python.tutorials.helpers as helpers
name= "scnn+fc/"
INIT_NET = name+"/init_net.pb"
PREDICT_NET = name+"/predict_net.pb"
#read protobuf
with open(INIT_NET,"rb") as f:
    init_net = f.read()
with open(PREDICT_NET,"rb") as f:
    predict_net = f.read()

# you must name it something
workspace.RunNetOnce(init_net)
workspace.CreateNet(predict_net)
p = workspace.Predictor(init_net, predict_net)

input = np.ones((1,1,63,13))
# submit the image to net and get a tensor of results
results = p.run(input)
res= np.asarray(results)
#response = helpers.parseResults(results)
# and lookup our result from the list

这是我最初的.prototxt

Answer 1

p.run期望的类型是输入列表。

更改：

p.run(input)

出自：

p.run([input.astype(np.float32)])
