Hello, is there a link to the instructions available somewhere? This one seems to be broken.

Hello) Has anyone had a problem installing nslr to visual studio? How to solve it?

note: This error originates from a subprocess, and is likely not a problem with pip. error: legacy-install-failure

× Encountered error while trying to install package. ╰─> nslr

note: This is an issue with the package mentioned above, not pip. hint: See above for output from the failure.

@user-480f4c Thank you. One question aditionally however. If i get the heatmaps, i can't really download the data for them in a .csv format, can't i? In case i want to work with this data statistically. e.g. a Principal Component Analysis

Hello, I want to know if there is any differences in the data sent to the cloud service and the data that is sent back into iMotions when using the ip adress of the phone to stream the eye tracking data.

If you need more information let me know

@user-07e923 I hope its fine i ping, Who is able to answer this question?

I see, thaks for the information

okay i see. because we have a client experincing issues with connecting the companion app with iMotions to stream the live feed into iMotions

they do not have issues with the app natively or with the cloud

they have issues with establising the connection when they enter the ip adress of the phone into iMotions

the adress stated in the companion app

I was wondering it seem to have blinks detected that are in reality saccades and blinks not detected but there is a blink (observed on a plot of x/y coord), also even if a blink is detected there is coord x/y (even if eye close ?), weird no? I'm a little bit confused about those observation is this normal? (for precision I plotted x and y (2 curves) and over fixations from fixation.csv and blinks from blinks.csv all of these from the cloud download section)

Hello Pupil-labs team, in our recording setup, we are using MATLAB with pl-neon-matlab to start/stop recording and send_event to set events in the connected glasses. In a minimum working example, everything is working fine. As soon as we have a recording with many events (mutiple per second, can be some 10ms apart), the events are not visible in the cloud. In the MATLAB log, there is no error indicated when the events are sent to Neon.

Are there any limitations that we should be aware of? Anything that can lead to the events being dropped/purged?

Sure

Hello, 👁 core I am trying to use the IPC backbone to get real-time data, but for some reason, I don't see anything. I did see data just once in about a dozen times that I tried. Here is the code I am using (taken directly from the dev guide):

import zmq
import time
import msgpack

ctx = zmq.Context()
# The REQ talks to Pupil remote and receives the session unique IPC SUB PORT
pupil_remote = ctx.socket(zmq.REQ)

ip = 'localhost'  # If you talk to a different machine use its IP.
port = 50020  # The port defaults to 50020. Set in Pupil Capture GUI.

pupil_remote.connect(f'tcp://{ip}:{port}')

# Request 'SUB_PORT' for reading data
pupil_remote.send_string('SUB_PORT')
sub_port = pupil_remote.recv_string()

# Request 'PUB_PORT' for writing data
pupil_remote.send_string('PUB_PORT')
pub_port = pupil_remote.recv_string()

subscriber = ctx.socket(zmq.SUB)
subscriber.connect(f'tcp://{ip}:{sub_port}')
subscriber.subscribe('gaze')  # receive all gaze messages
subscriber.subscribe('pupil.0.2d.')

while True:
    topic, payload = subscriber.recv_multipart()
    # print(topic + "lol")
    message = msgpack.loads(payload)
    print(f"{topic}: {message}")

The code runs fine, but there is no output (I am using a notebook to run this, and it worked once, but I haven't been able to get it up and running again). I am not sure what I am doing wrong here, any help would be appreciated!

EDIT: Nevermind, I realized that I have not been calibrating before I start using it, sorry for the unnecessary post, and thanks!

Hi, I have located some dependency issues. It seems I can't have a python environment with both pupil-labs-realtime-api and pl-neon-recording ~~installed~~ working. It seems protobuf needed for real time API is v3.18.0 (which is a yanked version as per PyPI), and neon recording library seems to pull the latest protobuf -- with the result that in the python environment containing both libraries, the protobuf 3.18.0 is installed. Normally, I won't bother about dependencies, but it seems pl-neon-recording would not play with the older protobuf version. Could you kindly address this -- such that I can use both libraries in a common environment?

I provide a listing to substantiate what I have described above.

Good morning, everyone! I need some help. I've been developing with Pupil Labs and HTC Vive on Unity for months, but I've never been able to fix the background during calibration. When the calibration is activated before an experiment, the background doesn't darken and turn gray as it does in the demo; instead, it stays transparent, showing what's in the experiment room. Does anyone know if I need to manually add the gray background, or have I configured something incorrectly?

Hi, I am trying to read back events that I issued while recording using the real-time API with pl-neon-recording (I'm on 0.1.6 version), after having fetched the exported recording. I clearly have events in the file:

wc tmp/Neon\ Export/2024-08-28-16-01-31/event.txt
      10      10     174 tmp/Neon Export/2024-08-28-16-01-31/event.txt

On the shell:

>>> import pupil_labs.neon_recording as nr
>>> recording = nr.load('tmp/Neon Export/2024-08-28-16-01-31')
>>> recording.streams
{'audio': None, 'events': None, 'eye': None, 'eye_state': None, 'gaze': None, 'imu': None, 'scene': None}
>>> recording.gaze.ts[:10]
array([1.72485729e+09, 1.72485729e+09, 1.72485729e+09, 1.72485729e+09,
       1.72485729e+09, 1.72485729e+09, 1.72485729e+09, 1.72485729e+09,
       1.72485729e+09, 1.72485729e+09])

>>> recording.events.ts[:4]
Traceback (most recent call last):

KeyError: 'event'

I seem to lazy-load other data streams, but when I try to read events, I run into issues. I suppose the library has some internal confusion around the keys "event" and "events"... Could you have a look please and advise? Thanks.
