where you get this issue? I just run the Walkthrough and works fine for me
I got it in Spyder 5
meant which part of the code, like a full stacktrace would be nice, I need more info to check that, I dont use spyder, using jupyter notebook
Ok: pasting full error info:

ahmmn, its downloading orbit information from web, I can only reproduce this if I disable internet, you sure you have internet access? I guess you have to investigate on your end here
maybe also try deleting the cache dir /tmp/gnss
Yes, my internet works fine. Do you have any ideas what should I check ?
check the cache directory if it downloads anything, on the first run you should see the download lines like:

Yes, I have it, now the tmp/gnss has some rusian products and cddis products, but the error in console is still the same EDIT: the last call from the console is: Downloading https://github.com/commaai/gnss-data/tree/master/gnss/products1983/igu19830_00.sp3.Z Traceback (most recent call last):

yea that url doesnt exist, that would explain it, cant really tell tbh, seems something is off in the downloader, best to track down why the download of the other orbits is not working
Hm strange, I checked if my astro dog and downloader file is the same with that one at github and its excactly the same code... I'm not an expert so its difficult for me to find out the issue, but thanks for help, I appreciate that
another guess might be that the default cache dir doesnt work for you as its /tmp/gnss
and you are on Windows right? maybe changeing it might already fix it
sure no problem, let me know when you found it
I just installed laika library, and everything looks ok but I'm getting an error: No orbit data found. For Time 2018-01-07 00:00:00 constellations ['GPS', 'GLONASS'] valid ephem types (<EphemerisType.FINAL_ORBIT: 1>, <EphemerisType.RAPID_ORBIT: 2>, <EphemerisType.ULTRA_RAPID_ORBIT: 3>)
even when I'm using excactly the same code that is provided in Walktrough. I must say that I'm getting this error for any consellation and time I use. I tried with python 3.11 and 3,8.0
