# 输出层
Wout = weightVariable([512,2])
bout = weightVariable([2])
#out = tf.matmul(dropf, Wout) + bout
out = tf.add(tf.matmul(dropf, Wout), bout)
return out
问题1：第二行bout这里为什么给的是权值，不应该是给偏差值吗？（The second row “bout” here why give "weightVariable“, should not be given ”biasVariable”?）
2
def is_my_face(image):
#run(fetches,feed_dict=None,options=None, run_metadata=None)
#tf.Session.run()执行fetches中的操作，计算fetches中的张量值。返回值为fetches的执行结果
res = sess.run(predict, feed_dict={x: [image/255.0], keep_prob_5:1.0, keep_prob_75: 1.0})
if res[0] == 1:
return True
else:
return False
问题2：res = sess.run(predict, feed_dict={x: [image/255.0], keep_prob_5:1.0, keep_prob_75: 1.0})
res[0] == 1这一句看不懂，为什么==1就是真了？ （Res[0] = = 1, this sentence does not understand why ==1 is true?）

我在做本科毕设，有些问题不懂，可以加好友请教一下吗？QQ1198265517 微信xu17862702083
非常感谢你！

sometimes it happened,when running to a hundredfold,anyone can handle it,please tell me,thank you so much !

比如get_my_faces我用摄像头提取了10000张自己的照片，如果is_my_face运行时候是别人，比如是Tom的坐在电脑前，那么怎么能判断出这个人是谁?目前是不是只能判断出是不是自己，判断不了具体是谁？

请问这个项目还在继续研发吗？方便建个qq群一起交流开发吗？

打扰了，已经解决。

功能比较单一，只能识别本人，而且识别度好像不算太好，有他人来的时候也显示true，希望在博客中也能介绍一下整个模型搭建的原理之类的，对初学者可能更加友好

ok very good

can you tell me the result that if it is correct,and i train my own model ,i test this but it is not correct .thanks

您好，神经网络最后一层神经元的个数是等于训练数据中人员数量吧。但如果实际应用中，那个人不是训练数据中的人，那么向量匹配时会不会有什么影响，还是得重新训练网络？

在进行测试的时候，真人识别情况下，每个人都识别为我的脸，如果用照片，则显示结果正确，为何？

  您好！我看了您的博客和本项目，严格按照您博客的说明步骤进行，但是在第一步时我只拍了4k张照片。

在第二步时，执行“train_faces.py”源文件时，发生了如下错误：
InvalidArgumentError: You must feed a value for placeholder tensor 'Placeholder_1' with dtype float and shape [?,2] [[node Placeholder_1 (defined at F:/ProgramDesign/Python-Spyder/FaceRe/train_faces.py:69) ]]

我对您的代码修改了两处：
  注释了train_faces.py的第10行代码：# other_faces_path = './other_faces'
  注释了train_faces.py的第50行代码：# readData(other_faces_path)
我的运行环境：win10、TensorFlow1.13.1、Python3.6、Anaconda Spyder3.3.4；

请问这样该如何解决呢？(菜鸟自学AI，所提问题若有冒犯，还请见谅！)

OpenCV(3.4.1) C:\Miniconda3\conda-bld\opencv-suite_1533128839831\work\modules\imgproc\src\color.cpp:11147: error: (-215) scn == 3 || scn == 4 in function cv::cvtColor
出现这个报错，怎么查都找不到是啥原因

摄像头得到的RGB难道不是0~255？求教

I have a question whether the project was completed by yourself?

如题，train_test_split是不是不在sklearn这个包了？

请问：cv2.error: OpenCV(3.4.2) /io/opencv/modules/imgproc/src/color.hpp:253: error: (-215:Assertion failed) VScn::contains(scn) && VDcn::contains(dcn) && VDepth::contains(depth) in function 'CvtHelper'
这是为何

请问您遇到过这种情况吗?网上说是图像文件为空,但是我设置了判断也无济于事,期待您的回复!

from sklearn.model_selection import train_test_split出错，这个train_test_split是什么?

程序能运行，本人在摄像头前面的时候可以识别，Is this my face? True。
但是我用手机自拍然后把照片放在摄像头前面就识别不出来，Is this my face? False
请问这是怎么回事？

saver.restore(sess, tf.train.latest_checkpoint('.'))
报错为值为none

为何不论识别谁都显示True呢

楼主，您好！
当我运行运行is_my_face.py文件时，出现File "D:\Anaconda\envs\tensorflow\lib\site-packages\tensorflow\python\training\saver.py", line 1264, in restore
raise ValueError("Can't load save_path when it is None.")
ValueError: Can't load save_path when it is None.
请问我应该如何解决这个问题，是什么原因导致了错误了呢。期待尽快得到你的回复。谢谢

File "G:/pycharm/untitled1/venv/is_my_face.py", line 145, in
saver.restore(sess, tf.train.latest_checkpoint('.'))
File "G:\Anaconda\envs\tensorflow\lib\site-packages\tensorflow\python\training\saver.py", line 1751, in restore
raise ValueError("Can't load save_path when it is None.")
ValueError: Can't load save_path when it is None.

How to tackle this problem? Thanks!

整个python文件运行时没有出现报错，但就是没有生成相应的model文件，想请加下是什么问题

运行is_myface:
Traceback (most recent call last):
File "C:\Users\Administrator\Desktop\Facerecognition (1)\is_my_face.py", line 135, in

Hi! I ran your code and found that accuracy is not high ,as for me I wore the glasses so I found some glasses man but code think that it is me....
so HOW CAN I IMPORVE FACE RECOGNITION ACCURACY?
HOW TRAIN ? AND HOW TO IMPORVE REFUSE POSSIBILITY?
THANK YOU！

python的cv2安装不上，能不能用别的框架替换一下？？

不好意思,问题已解决

您好，我学习您项目时候，通过摄像头获取自己的脸时候，时间很长，用了接近4小时才获取到10000张自拍，问一下您知道是什么原因吗？我用的是dlib

小弟幾個月前也在做類似的東西, 參考作者的圖片輸入,
發現原來之前自己對於圖片內容想法是錯的,
經修改後, 再參考作者卷積層加入dropout的想法, 成功實現相同功能~
但小弟這邊有個問題
神經網路中：
#全連接層
Wf = weightVariable([8*16*32, 512])
小弟覺得是: Wf = weightVariable([8*8*64, 512])
雖然結果是一樣的, 但意義感覺不一樣
想問問作者您怎麼覺得是: Wf = weightVariable([8*16*32, 512]) 呢~

请问，您是用pip 还是pip3？

在运行get_my_face时缺没有这个问题。
