Hi @&288503824266690561 , I want to know about the total pupil cloud storage space. How much space a single user can get on pupil cloud to store the data. Is there any option to increase the storage capacity on pupil cloud? please let me know. In my project eyetracker data is quite large so I need more space for the storage on pupil cloud.

Hi @user-dc5cba ! Cloud uses its own algorithm for fixations (which is different from the one that traditionally Pupil Player used) you can read more about it and find the whitepaper here https://docs.pupil-labs.com/invisible/basic-concepts/data-streams/#fixations

Is there any reason why you don't want to use Cloud? We plan to release the code and an offline tool to obtain the data as from the Cloud, I will keep you posted on that

Hi, a few weeks ago I built the denspose module from the alpha lab on a linux machine and it worked fine. Now, on a different linux machine, hence new environment, i'm trying to install it again but the github installlation command (python -m pip install torch 'git+https://github.com/pupil-labs/densepose-module.git') isn't working; ie I'm having this error:

ERROR: Could not find a version that satisfies the requirement torchvision==0.15.2 (from pupil-labs-dense-pose) (from versions: 0.1.6, 0.1.7, 0.1.8, 0.1.9, 0.2.0, 0.2.1, 0.2.2, 0.2.2.post2, 0.2.2.post3, 0.3.0, 0.4.0, 0.4.1, 0.4.2, 0.5.0, 0.6.0, 0.6.1, 0.7.0, 0.8.0, 0.8.1, 0.8.2, 0.9.0, 0.9.1, 0.10.0, 0.10.1, 0.11.0, 0.11.1, 0.11.2, 0.11.3, 0.12.0, 0.13.0, 0.13.1, 0.14.0, 0.14.1) ERROR: No matching distribution found for torchvision==0.15.2

I've tried installing another another torhvision but then I don't know how to finalise the installation of the pl-densepose module. Could someone help me with that?

@user-20a5eb just to follow up I will try to update the readthedocs ASAP https://densepose-module.readthedocs.io/installation.html

is anyone on this. I'm trying having trouble with pylsl and pupil capture

idk im just going to ask the full question here

I'm using linux, ubuntu 22.04. I have the pupil invisible and I want to use lab streaming layers capture relay plugin. I am doing this all within a conda environment. So I symlinked the "plugins" subdirectory of the capture_settings folder in the home directory to my conda environments pupil_capture_settings/plugins subdirectory where I have pylsl/lib and the plugins I want. I have followed the documentation but I'm very new to this. First when I downloaded lsl it gave me 3 shared libraries, two of which seem to be symlinks. 1 doesnt lead anywhere, the other says it could not be displayed as there is no application for it. These are the liblsl.so and liblsl.so.2. The one I copied into the /pylsl/lib is liblsl.so.1.16.2. However the capture log within the conda environment produces no changes but the capture log of the home directory's pupil_capture_settings does produce an error. Which is: 2023-09-01 16:39:43,962 - world - [WARNING] plugin: Failed to load 'pylsl'. Reason: 'LSL binary library file was not found. Please make sure that the binary file can be found in the package lib folder (/home/alexfarac/pupil_capture_settings/plugins/pylsl/lib). I have also tried to the specify the environment variable but I'm not sure I did that correctly.

my python version is 3.7 as well

please let me know if you need more information

Hi @user-20b523 ! Pupil Invisible is not compatible with Pupil Capture. If you would like to use Pupil Invisible with LSL you will need to use the LSL relay for Invisible and Neon. https://github.com/labstreaminglayer/App-PupilLabs?tab=readme-ov-file#pupil-invisibleneon-lsl-relay https://pupil-labs-lsl-relay.readthedocs.io/en/stable/

we do have pupil core as well

Honestly. I'm not even using the glasses im just trying to have the plugin load to the pupil capture application

i was going to use them later but if they don't work we can just use the pupil core then

and if I were to use the invisible instead. which pupil_---_settings directory would i place the plugin

@user-20b523 With Pupil Labs LSL relay ( 🕶 invisible and 👓 neon ) there is no need to place it anywhere, simply install the python package pip install lsl-relay and run it with lsl_relay https://pupil-labs-lsl-relay.readthedocs.io/en/stable/index.html

With 👁 core, it is a bit more complicated, you will need to place this folder https://github.com/labstreaminglayer/App-PupilLabs/tree/master/pupil_capture in the plugins folder of Capture. In the same plugin folder you will need to place pylsl https://github.com/labstreaminglayer/pylsl/tree/master/pylsl

btw is it possible to do within a conda environment?

for both the core and invisible

and does the lsl-relay require pylsl or are you saying it really just requires me to install the plugin and nothing else

thank you. Would there be any issues having both on the same computer? since it would mean i would have two pylsls?

ok thank you

I'm doing it for pupil relay but this is what I recieve in the terminal when i input lsl_relay: Traceback (most recent call last): File "/home/alexfarac/anaconda3/envs/pupinvenv/lib/python3.7/site-packages/pylsl/pylsl.py", line 1287, in <module> libpath = next(find_liblsl_libraries()) StopIteration

You can install the LSL library with conda: conda install -c conda-forge liblsl or otherwise download it from the liblsl releases page assets: https://github.com/sccn/liblsl/releases

what i did for the above was create a conda environment. I installed pip, python 3.7, and lsl-relay 3.1.0

i it

in

ive done both but still get the error

i put all the library files in but now its saying this: Traceback (most recent call last): File "/home/alexfarac/anaconda3/envs/pupinvenv/lib/python3.7/site-packages/pylsl/pylsl.py", line 1288, in <module> lib = CDLL(libpath) File "/home/alexfarac/anaconda3/envs/pupinvenv/lib/python3.7/ctypes/init.py", line 364, in init self._handle = _dlopen(self._name, mode) OSError: libpugixml.so.1: cannot open shared object file: No such file or directory

apparently i needed to do this command: conda install -c conda-forge libstdcxx-ng=12

and it works now

Hi, sorry to distrub, I'm recording a dataset with Pupilabs Invisible. I was interesting in the sensor model employed for the RGB images, but I couldn't find this info. Is it possible to have this information? Thank you

@user-dc2c1d hi anuj here. We have sent an email regarding our pupil glasses. We haven't yet received the the delivery. Kindly check the mail and let me know

Hi, thank you for the answer. Yes, since we are planning to collect a big dataset we wanted to know the exact manufacturer and sensor model mounted on the eye tracker, if it is possible to have this information. This is because on the website only high-level information are provided, like the image size and fov, but not the low level info. Thank you

Hi all,

We are having some problems with a recording being uploaded to the cloud. It has been stuck at 99% upload to cloud for a few days. We have tried (1) turning the phone on and off, (2) restarting the phone, (3) restarting pupil companion app, (4) changing wifi settings to different connections, (5) we recorded something after that video and tried to see if this would initiate the upload to cloud but it won't. Not sure what else to do for troubleshooting...

@user-dc2c1d hi anuj here, plz update me on our package sent from your side.

If you have a Pupil Invisible device

Hi, @nmt Do we fix the scen camera frame rate video capturing in pupil Invisible? If yes, then how?

Hi, we have a problem of recording uploading failure. The Oneplus Version is Hydrogen OS 11.0.12.12.IN21 and the Invisible Companion app version is 1.3.-prod. Could this uploading failure happen because of the old version of app or phone? I dare not to upgrade the phone android system as I saw a notice of avoiding upgrading the android system.

Hi, I have a problem downloading the latest version of Pupil Invisible Companion due to the VPN problem. Could anyone help and send the latest app of companion to my email [email removed] Great thanks!

i have a recording of scene camera video of pupil invisible. i am surprising to see that the rcorded video frame rate is not constant throught the video duration. It vary trought the video and when i am checking the frame rate in video properties it gives average fps of the video. Does any way is possible so that I can fix the fps of scene camera video throught the duration of video. Varying fps is creating problem to me in analysis the data. Anyone from pupil invisible please help me to resolve tis issue.

Hi Neil @nmt New problem raised!😭 now my one plus phone stuck at the process of Invisible Companion LOGIN which could not visit the pupil labs server and always stay at the login page shown in the below picture. My android phone version is Hydrogen OS 11.0.15.15. IN21. I tried the following methods to fix the login problem but all failed: 1. I tried to install four different companion versions including 1.3.0-prod, 1.3.1-prod, 1.4.28-prod, 1.4.30-prod, downloaded from Apkpure.com. 2. I double checked and used the same exact account name and password of Pupil Cloud which I could log in successfully on my laptop website for multiple times. 3. I also tried the mode of VPN and VPN-free network connection.

I have tried the speed test link you provided in both VPN and VPN-free network mode. The VPN network mode provides the data variation information and the VPN-free one does not.

Great thanks for your helps!

@nmt Hi Neil. Thanks for your response. I am not able to use Google Play store 😂 Could you please send me the latest app version of Companion? I have struggled for a week but failed to manage the downloading issues from Google play. My email address is [email removed]

Hi, I started the enrichment to create a Reference Image Mapper yesterday, but it is still processing today. Is it normal?

Hi, I've recorded a few videos and want to cut the set up and end parts. Previously, I did that with Pupil Player, now when I put my folder in the Pupil Player the video never launches. How can I cut the videos efficiently? I also used to do it with ffmpeg but I noted that it's not the best idea from a previous message. Do you have any advice on that?

Hi @user-20a5eb 👋 First things first, can you please check if you are uploading the "Pupil Player format" of the recording export in Pupil Player? With the introduction of the new UI of Pupil Cloud, the process for accessing this export format has slightly changed. To enable the download of this format, please follow these steps:

• Go to your workspace settings.
• Enable the "Show Raw Sensor Data" toggle.

Once you've completed these steps, when you right-click on the recording and select "Download," you should now see the "Pupil Player format" available as a third export format option. Please download the recording in this format and try again to upload it to Pupil Player.

Please let me know if this solves the issue.

I'm having a bit of trouble. I have a few events in my recording and i'm trying to match its timestamp with the timestamp within the fixations data. Has anyone had an issue like this? seems like some timestamps don't match. Or if you have any other advice on matching it within the fixation data to do further analysis. Much appreciated!

Hi @user-91d7b2 ! I'm not sure I fully understand your question. Could you please clarify? Do you want to get fixation data between two specific events?

Hello colleagues! We need your help! Our recordings are not uploaded to the cloud and a calibration error is displayed. The phone is connected to the Internet. What could this be and how to solve this problem? Attached are images of the error.

Hi @user-0a5287 ! Would you mind performing this test ? https://speedtest.cloud.pupil-labs.com/

Hi @user-91d7b2! You can easily obtain fixation data within your time of interest. Let me give you an example.

Assuming you have a recording and you want to get the fixation data within a specific time frame of this recording (let's call the events defining this period of interest "eventA_start"and "eventA_end").

You can create these events in Pupil Cloud, and once you download the data you should be able to see the name of these events with their associated timestamps in your events.csv file. Then you can filter out some fixation data as shown in the following snippet:

import pandas as pd

# Load the events.csv and fixation.csv files into dataframes
events_df = pd.read_csv("events.csv")
fixation_df = pd.read_csv("fixations.csv")

# Find the timestamps for the "eventA_start" and "eventA_end" events
start_timestamp = events_df.loc[events_df["name"] == "eventA_start", "timestamp [ns]"].values[0]
stop_timestamp = events_df.loc[events_df["name"] == "eventA_end", "timestamp [ns]"].values[0]

# Filter fixation data within the specified time range
fixations_during_event = fixation_df[(fixation_df["start timestamp [ns]"] >= start_timestamp) &
                                     (fixation_df["start timestamp [ns]"] <= stop_timestamp)]

# Calculate the number of fixations and average fixation duration
num_fixations = len(fixations_during_event)
average_fixation_duration = fixations_during_event["duration [ms]"].mean()

# Print the results
print("Number of Fixations:", num_fixations)
print("Average Fixation Duration:", average_fixation_duration)

I hope this helps!

Hello! Pupil Labs' members. I emailed [email removed] but I hope I can answer my question from here. See, at my University, in Brazil, we're building a Laboratory and we got interested in buying the Pupil Invisible Neon. However, the professor who is going to bring the equipment to Brazil is leaving Europe in two weeks. We would like to know if there are copies of the equipment available for immediate delivery.
