ValueError: Error when checking : expected input_1 to have 4 dimensions, but got array with shape (50, 50, 3)
原因：预测的时候给的是数组，需要转成array，np.asarray(imagelist)
下面是正确代码：
path =
'../../white_mouse_data/test/1/'
# path=r"D:\git_project\mouse_detect_demo\mouse_data\0_test\\"
files = os.listdir(path)
aaa =
0
index =
0
imagelist = []
for file
in files:
a = cv2.imread(path + file)
a=cv2.resize(a,(IMG_SIZE,IMG_SIZE),
interpolation=cv2.INTER_CUBIC)
imagelist.append(a)
t0 = time.time()
result = model.predict(np.asarray(imagelist))
