Failed to download all of LAION-400M #277

Closed zw615 closed 8 months ago

zw615 commented 1 year ago

Hi, I have been trying to download LAION-400M, using the same instructions you provided, however, the download is not complete. On a rough estimation, the success rate is about 0.83-0.85. So for a 400M size dataset, I actually get 350+M samples. Here is the content of a typical stats.json file

Also, according to the OpenCLIP example running code, they get a total of 41455 shards for LAION-400M. But I only get 41408 shards, which is 47 shards less. I used the default number_sample_per_shard=10000, so I am not sure why there is this difference.

I wonder is that normal? How can I download all the 400M data? Thanks a lot!

BTW, I have searched and found a similar issue here, where it is suggested to set up knot resolver for DNS resolving. However, I did set up the knot resolver exactly as the doc, and checked it by dig @localhost google.com. So I think the problem is not the DNS resolver.

Hi,

I think that's as expected, there is 1% link rot per month and it's already been more than 8 months since initial release, so success rate went from 95 to 87

You may be able to increase this a little bit by changing the user agent.

You could decide to get more samples by downloading laion2B-en instead

Hi I tried to download but the size of tar only gets ~20MB and the number of files in file tar gets ~2200 files, this is the command I used

img2dataset --url_list laion400m-meta --input_format "parquet"\
         --url_col "URL" --caption_col "TEXT" --output_format webdataset\
           --output_folder laion400m-data --processes_count 16 --thread_count 128 --image_size 256\

No, I don't set up knot resolver, I will try to set up the package and try again, thank you.

how can I fix this error?

update: This is log from wandb

rom1504 commented 1 year ago

You should set up only knot resolver, not bind9 and also disable your previous resolver ( eg systemd-resolved)

You can make sure this is working by looking at the CPU usage of Knot in top/htop

Then you can check the error reasons in wandb or in json files in the output folder

yes, I tried to only use the knot but the rate failed ~0.6 for each shard, I added more DNS into the /etc/resolv.conf and re-download again, the results seem better than before.

hello~ I recently faced a similar problem with the download rate and the knot resolver couldn't help. Could you please share more details or steps on how you modified the DNS to improve the download rate? Many thanks!~

faithfulnguyen commented 9 months ago

yes, I modified the file /etc/resolv.conf because the internet in my company, here is some public DNS I used to download the dataset

nameserver 8.8.8.8
nameserver 8.8.4.4
nameserver 76.76.2.0
nameserver 76.76.10.0
nameserver 9.9.9.9
nameserver 1.1.1.1
nameserver 1.0.0.1

one more thing, you could try to reduce the number processing count and thread to increase successful rates, because my bandwidth is limited, I need to change the config to adapt with my env, I used --processes_count 2 --thread_count 32. The tradeoff between speed and successful rates is just my experiment, not sure that config works with you but you could give it a try. hope that thing helps you.

Yes, I also observed that by reducing the number of processes, my success rate went up quite a bit and I stopped getting DNS errors like: "<urlopen error [Errno -2] Name or service not known>".
