I have an other Problem with cli.display_image(im, 5.0), the duration time has no effect. Cozmo Displays the Image but falling back to eyes before duration time is finished. I injected simply print("duration start" ) and print("duration stop") to the display_image function. The sleep Part works but cozmo clears the Display before sleep finished.
Hi @snowgoon88!
I am not sure why you are seeing these issues. I have been trying to reproduce them now in a couple of cozmos and python versions, but things seem to be fine on my side.
From what you comment and looking around the code, I am thinking that the issue might be with the conversion from array (that comes from the procedural face generator) to PIL Images, or when loading the image in the ImageEncoder
.
About your questions:
Debugging pycozmo and most of the scripts is not trivial, since stopping the scripts at any time makes the connection to the robot drop, which makes debugging a bit difficult. Nevertheless, you can easily try to debug it with any typical python debugging tool, if you clone the repository and run the scripts from there. The procedural_face
and procedural_face_expressions
scripts are quite similar: They work very much the same as the display_image
, only using a generated image instead of one loaded from a file. This way, procedural_face
loads a single image while procedural_face_expressions
loads images of each expression and intermediate states are generated and sent to the robot. Both scripts should show cozmo's eyes with different expressions.
The enable_procedural_face
flag is used to control wether the automatic generation of faces for cozmo is enabled. This is a feature more complex than what is shown in the example files, where you can load a procedural face statically. When enable_procedural_face
is True, the robot will show its eyes moving as long as no other animation is shown. In the procedural_face
and procedural_face_expressions
scripts, this feature is disabled so that you can test different expressions without being confused by other movements of the eyes that might happen before or after the animation.
I wish I knew hahaha Now seriously, I believe something might be failing with PIL, but I'm not sure. How have you installed the package? what version of PIL and Pillow do you have installed?
Hey @faildproject, I took a look at the issue you mentioned. I am working on a fix for it now, it is actually a quite small issue so we should have it ready soon.
Hi all !
Looks like I have issues similar to Snowgoon's when trying to display messages on Cozmo's screen. As a matter of fact, I think we may both have the exact same problem, as I also get strange diagonals, and can't see no eyes... and just like Snowgoon, display_lines.py
works fine.
I know this issue is opened for quite a long time now, but any help would be greatly appreciated. In particular, if @snowgoon88 solved the problem, please let me know !
Thank you in advance !
For all intents and purposes, here's what I get when running one of the examples:
2022-02-09 13:51:18.898 pycozmo.general INFO Firmware version 2381. 2022-02-09 13:51:18.944 pycozmo.general INFO Body S/N 0x43216893, HW version 5, color 3. 2022-02-09 13:51:36.374 pycozmo.general INFO Done.
and here are the packages and versions I'm using (with Python 3.7.0):
Package | Version |
---|---|
dpkt | 1.9.7.2 |
flatbuffers | 2.0 |
numpy | 1.21.5 |
Pillow | 6.0.0 |
pip | 22.0.3 |
pycozmo | 0.8.0 |
setuptools | 60.6.0 |
wheel | 0.37.1 |
EDIT: problem solved
I updated Pillow to the latest version, and it worked fine. I had installed version 6.0.0 as mentioned in the requirements field in Pycozmo's main README, turned out it wasn't the good one, apparently. I don't know if the issue I was facing is linked in a way or another to any of my other local specs, but if Pillow v. 6.0.0 used in conjunction with Python/PyCozmo/Packages versions specified above yields reproducible similar problems, it might be worth mentioning it in the README.
Hope this can help, Antoine
Hello everyone,
I think I have some problem with displaying things on my cozmo...
Preliminary : using the Anki android application, I have no problem with Cozmo display (display wifi info before logging, expressive eyes, games...).
When I run the pycozmo examples dealing with display:
display_image.py
: shows "Pycozmo" but sometimes also "strange" lines, like truncated diagonales (as if some values where also written in the display memory buffer).display_lines.py
: works ok I think. I see a moving triangleBut, I have a black screen when I try:
procedural_face.py
procedural_face_expressions.py
(I have checked that
procedural_face_show.py
displays an image with two eyes using PIL on MY screen.Besides, and I do not know if it is related, but I think that my first tries with pycozmo.client, the robot was displaying random eyes (a bit like the Andy app). Now, it keeps a black screen.
So I have questions (and maybe I'm using the pycozmo module the wrong way).
1) How can I debug the
procedural_face
andprocedural_face_expressions
scripts ? They should display something on the cozmo, no ?2) What is the use of the
enable_procedural_face=False
while connecting to the client in these 2 scripts. I tend to think it is to stop the default display of random eyes. But in my case, with other application/examples, when it is set toTrue
by default, nothing happens : black display for cozmo.3) What am I doing wrong ? (Or what did I do wrong to make the default procedural face to be shut down "permanently" ?)
