[@richieT737]

Firstly an excellent tutorial, very well presented. I had a couple of issues with the code and I offer solutions for these in case anyone has the same. Firstly I added the following line of code to remove the file extension for a nicer display: name = self.known_face_names[best_match_index] # remove the file extension for a neater display name = name.split('.')[0] I also found with more than one face it would call everyone by the same name. This is because the zip line repeats until the shortest tuple is completed then stops. If a single face is in frame for a while before a second face appears only the first will be annotated. To fix this I reversed the names and location lists to give a last in first out solution. Change line to: for (top, right, bottom, left), name in zip(reversed(self.face_location), reversed(self.face_names)): I hope this helps someone.

[@rayendammak7303]

can you provide us with the code , thanks :)

[@morbid1134]

You said "firstly" twice and had no "secondly."

[@BeckyBenton]

Lovely tutorial. I did have a bit of a problem at runtime with small_frame[:, :, ::-1]. I fixed it by calling this, instead: cv2.cvtColor(small_frame, cv2.COLOR_BGR2RGB)

Apparently the source code mentioned near 5:00 in video is well hidden. Otherwise, the video is informative. At 75, I like to follow along with the code. Sometimes I do try the code and sometimes not. The source code does make it handy for me when it isn't so well hidden.

[@asifrehman4214]

Hi Author Its a great article... with perfection... 1) If a show a pic consisting of multiple faces then it only detect just one face at a time...What is the reason for it? 2) Its quite slow as well... Can you guide on these two aspects. A great video.

[@abdulrahmansabri4547]

thank you so much for such a huge effort, when trying recognition, it is lagging too much, do you have any idea about what is the problem? thanks in advance

[@MrNosiks]

I changed the line and it worked for me rgb_small_frame = small_frame[:, :, ::-1] rgb_small_frame = cv2.cvtColor(small_frame, cv2.COLOR_BGR2RGB)

[@enormousearl8838]

So can you only train it on one image per unique face? You can't give it multiple angles of the same face to help it recognize it better?

[@SolverMindEdu]

I dont know why but it says that the face recognition module is not able to be found, Even when I try to import the Face Recongition again it still just wont work. And all I did was try the first part. Is this a version issue or is this something else. Please check out this comment if you have time. Thanks!

[@cgsoldier4196]

Is it possible to dynamically add photos to the faces folder? For instance, if a face is detected that is not recognized, could the user possibly be promoted to take a screenshot and that picture will be saved to the faces folder and encoded like the others?

[@zhilaanrusmawan7913]

[@destanifountain]

I had the same issue and I'm STUCK

[@suldanhalaasi]

this because you don't have setuptools, to solve this open cmd and write this pip install setuptools , if this doesn't solve, then check your numpy version, to check it open cmd write pip list then check numpy version in the list, if it's greater than 1.26.4, then uninstall numpy like this, pip uninstall numpy and then open cmd write pip install numpy==1.26.4

[@Loopyengineeringco]

Same problem... 😢

[@Loopyengineeringco]

if you change "rgb_small_frame" to just "small_frame" on that line, it works. Not 100% sure why, maybe Python doesn't like the rgb_small_frame = small_frame[:, :, ::-1] bit at the end '::-1'

[@glmbrt2396]

​@@Loopyengineeringco you are right i had the same problem, i solved by changing "rgb_small_frame = small_frame[:, :, ::-1]" with "rgb_small_frame = cv2.cvtColor(small_frame, cv2.COLOR_BGR2RGB)" i hope it will solve your problem as well

Hello. I found your video is very important. Thank you for the tutorial. Now my question is I don't want to recognize the static images like photo copy or something else that is static because any person can recognize the face by scanning the static photo copy. So, is there any way to recognize only the live face? Like in your case, obama's photo is recognized but it should not be because any person can get the photo of obama from internet and he/she can just scan it.I hope you understood my question.

We’re sorry to hear that you’re facing trouble with this tutorial. We have some suggestions for you: 1. Try watching the tutorial again to check if you missed something (remember that programming languages are strict, and that uppercase & lowercase characters are completely different.) 
 2. If you’re facing an error, try copying and pasting it into the Google search engine, it’s the fastest way to find the best response for the issue you are facing. 
 3. If it’s still too confusing for you, try taking a step back and working on an easier project to try to improve your programming skills before tackling the project in this video. We wish you the best of luck with your project!
