no window stream

[juanmartin]

Hi, I finally managed to run tello_openpose.py only in CPU only mode on macOS High Sierra. I was not able to compile with CUDA and cudNN because of Caffe. My terminal shows lots of these: Tello: 16:27:55.145: Info: video data 378945 bytes 182.2KB/sec The problem is I don't see any window with the stream nor the pose recognition. Even tried taking off with the morse code trick. Tello just stands there. Am I missing something? Thanks for this great project.

[geaxgx]

The lines Tello: 16:27:55.145: Info: video data 378945 bytes 182.2KB/sec are good, it means the program receives the video stream from the drone. You don't see any window with the stream. Does it mean there is a window but it stays black, or there is no window at all ?

Can you try to use the keyboard to pilot the drone ? Press 'tab' to for the takeoff, then press 'backspace' for landing. To know which keys you can use, search for 'controls_keypress_QWERTY' in the file 'tello_openpose.py'.

You can also start the program with the option '-l info' or '-l debug' (more verbose) to have more messages. So, for instance: python tello_openpose.py -l info

PS: I am afraid that with just a CPU, you can't really use Openpose to control the tello. Have you tried openpose alone, after its installation ?

[juanmartin]

OK, tried a few things: I understand the video is streaming ok, but there is no window, not even black. Just the terminal log which I paste down below for python2.7 and python3

python tello_openpose.py -l info                       1 ↵  1670  13:31:41

As you can see neither tab or backspace do anything since I can only focus the terminal window. Log shows everything fine but no window is showing the stream, therefore cannot use commands to manually pilot the Tello.

Did a test opening openpose examples and couldn't open the webcam input one (running macOS High Sierra) but could open the media input one and it was terribly slow, even to start showing the window output. So I believe CPU only mode is the problem here. Of course I knew it would be slower but thought it would at least be worth trying. I'll keep trying to install it with CUDA and cudNN support to use the dedicated GPU. Is there a recommended version for CUDA and cudNN to install openpose in High Sierra?

Thanks!

From your log, the meaningful error is: File "tello_openpose.py", line 333, in init_drone self.drone.subscribe(self.drone.EVENT_LOG_DATA, AttributeError: 'Tello' object has no attribute 'EVENT_LOG_DATA'

Tello object is defined in the TelloPy package. Was there an update in TelloPy ? No, it doesn't seem so. I can see that EVENT_LOG_DATA is still well defined at line 30 of the file https://github.com/hanyazou/TelloPy/blob/develop-0.7.0/tellopy/_internal/tello.py So this error is very strange to me. If there is an error for "self.drone.subscribe(self.drone.EVENT_LOG_DATA,...", why there is no error for the very similar previous line in tello_openpose.py "self.drone.subscribe(self.drone.EVENT_FLIGHT_DATA,..." ?

Have you modified something in tello_openpose.py ? Because I see that self.drone.subscribe(self.drone.EVENT_LOG_DATA, is at line 333 whereas it should be at line 332.

For Openpose on High Sierra, I have no idea. Please have a look at the official repository: https://github.com/CMU-Perceptual-Computing-Lab/openpose

[juanmartin]

OK I just gave up. Been with this all day, at some point I was able to compile openpose with gpu support but then Caffe didn't have gpu support so not even openpose examples would run.

I think I have modified tello_openpose.py because of a multiprocessing issue. Last chance was to install Caffe with docker but I don't really understand it. I pulled the image and when ran it said that my NVIDIA driver was not detected even though I have it installed.

It's just too complicated and waay too discouraging to continue since every step has a new problem involved, and solving one thing creates a problem somewhere else. I'll just wait till I get an ubuntu or windows machine with a decent graphics card (have an old machine with Radeon graphics which are even more troublesome) to give this another go. Got sick of Mac-only problems and Ubuntu-only solutions.

Thanks for all, though.

[geaxgx]

Yeah, computer science can be very frustrating ! There is also the OpenCv version of Openpose that you can try. It only works on CPU but it should be faster than the original version of Openpose you have already tried, because OpenCV does a pretty good job in optimizing neural network inference. If you have a recent version of OpenCV (3.4.1+), you can take inspiration from : https://www.learnopencv.com/deep-learning-based-human-pose-estimation-using-opencv-cpp-python/ or: https://github.com/opencv/opencv/blob/master/samples/dnn/openpose.py It should give you an idea of the max speed you can get on your CPU.

[juanmartin]

Thanks! I'll give that openpose a try. I was actually thinking if I could migrate your project from openpose to another environment that doesn't depend con Caffe. Or even this: https://github.com/ildoonet/tf-pose-estimation Still researching, maybe I find a better solution for us mac users with discrete GPU.

[duncanmix]

I have the same problem but in this case i'm using windows, I changed this self.drone = tellopy.Tello(start_recv_thread=not self.use_multiprocessing) to this self.drone = tellopy.Tello(self.use_multiprocessing) because of a multiprocessing issue. There is no window stream and I can't control the tello with the keyword

[geaxgx]

@duncanmix Please change instead : self.drone = tellopy.Tello(start_recv_thread=not self.use_multiprocessing) to this self.drone = tellopy.Tello()
The self.drone = tellopy.Tello(start_recv_thread=not self.use_multiprocessing) can only work with my hacked version of TelloPy and I should modify the repository accordingly because it can't work with the official release of TelloPy. As long as, you don't use the "--multiprocessing" flag, it should work with the official release and with no argument to tellopy.Tello().

@geaxgx . I am having this issue too. seems to be issue in tellopy. sorry for my dumb question, have you run it again recently using current tellopy? thanks

@geaxgx @benjaminjacobreji WINDOWS Machine: I did self.drone = tellopy.Tello(start_recv_thread=not self.use_multiprocessing) to this self.drone = tellopy.Tello() And changed EVENT_LOG_DATA to EVENT_LOG in line 334 tello_openpose.py N then I was able to run the script with CPU_ONLY mode, I was even able to do the Morse_Code_Trick mentioned in your youtube Video n the drone was searching for the body, but no openpose key point detection was seen over my body, can u help me with this..? I checked keypoint detection after installing openpose with python script on WINDOWS, I was able to see keypoint detection on my body though very much low fps but still it was working. After doing the above 2 changes, though the script was working fine but was constantly getting errors in between like this, though I don't think this error has nothing to do with key-point detection:

@TejasTidke I have the same issue, did you solve it ?

me too. i hope we can make this run

I finally made the video stream run on windows for this. The issue was i am not running it as administrator in windows and firewall is blocking it. On windows, I suggest opening cmd as admin or if you are running it using pycharm or other python editor\interpreter, please run it as admin. Hope this helps and many thanks to Geaxgx for this projects. I am still getting mvo and bystream errors in the log but i can see the stream and the pose estimation. Maybe i dont have enough gpu as i am only using gtx980m and i dont have enough space and lighting in my small room to fully test it
