我在ubuntu 16.04.02 LTS上安装了带有python 3.5的opencv-3.2.0。我想运行以下脚本：
import cv2
import numpy as np
from keras.models import load_model
# laptop camera
rgb = cv2.VideoCapture(1)
# droidcam android
# rgb = cv2.VideoCapture('http://ipaddress:port/mjpegfeed?640x480')
# pre - trinaed xml file for detecting faces
facec = cv2.CascadeClassifier('/home/shubhamrathore/haarcascade_frontalface_default.xml')
font = cv2.FONT_HERSHEY_SIMPLEX
# loading saved cnn model
model = load_model('/home/shubhamrathore/Downloads/face_reco.h5')
# predicting face emotion using saved model
def get_emo(im):
im = im[np.newaxis, np.newaxis, :, :]
res = model.predict_classes(im,verbose=0)
emo = {0: 'Angry', 1: 'Disgust', 2: 'Fear', 3: 'Happy', 4: 'Sad', 5: 'Surprise', 6: 'Neutral'}
return emo[res[0]]
# reshaping face image
def recognize_face(im):
im = cv2.resize(im, (48, 48))
return get_emo(im)
while True:
_, fr = rgb.read()
flip_fr = cv2.flip(fr,1)
gray = cv2.cvtColor(fr, cv2.COLOR_BGR2GRAY)
faces = facec.detectMultiScale(gray, 1.3, 5)
for (x,y,w,h) in faces:
fc = fr[y:y+h, x:x+w, :]
gfc = cv2.cvtColor(fc, cv2.COLOR_BGR2GRAY)
out = recognize_face(gfc)
cv2.rectangle(fr,(x,y),(x+w,y+h),(255,0,0),2)
flip_fr = cv2.flip(fr,1)
cv2.putText(flip_fr, out, (30, 30), font, 1, (255, 255, 0), 2)
cv2.imshow('rgb', flip_fr)
# press esc to close the window
k = cv2.waitKey(1) & 0xEFFFFF
if k==27:
break
elif k==-1:
continue
else:
# print k
continue
cv2.destroyAllWindows()
我得到的输出是：

此外，当我在终端上运行'python'并'import cv2'时，不会引发错误：

我从源代码构建并安装它。这是什么错误？
答案 0 :(得分：0)
我认为python的版本不同。错误消息＆＃39; /home/shubhamrathore/anaconda3/lib/python3.6/site- packages / keras / engine / topology.py:1242：..＆＃39; show version是3.6，因为python路径不是常规的，我认为python3.6是由你自己构建的并且由脚本使用。但是你在shell上发出的命令是＆＃39; python3＆＃39;它显示的版本是Python 3.5.2。
