Modified (with no API keys) download script to make it work properly
Added cookies and headers to avoid ban from google drive and url modification to bypass antivirus warning.
Thanks for sharing. new errors occured.

So, I went on kaggle: kaggle datasets download -d rahulbhalley/ffhq-1024x1024
Perhaps another alternative... https://datasets.activeloop.ai/docs/ml/datasets/ffhq-dataset/
Has anybody solved this issue?

hi @nekita473 I am a newbee in this field so having a very hard time to download the dataset. could you please send me the modified script to download the dataset. I am trying to download it but getting Incorrect file size error or Google download quota exceed error my gmail: [email protected]
A workaround for the people trying to download in the command line, the following downloads the zip file with the 1024x1024 images:
wget "https://drive.google.com/uc?export=download&id=1WvlAIvuochQn_L_f9p3OdFdTiSLlnnhv&confirm=yes"
for the other files, just (start) downloading the file in the browser to get the file id* and replace it by the id in the url above.
*In Firefox, there is a "copy download link" if you right-click on the cancelled download. This link doesn't work directly in wget, but you can use it to get the file id.
... need to change line 35 in download_ffhq.py to: file_url='https://drive.google.com/uc?id=16N0RV4fHI6joBuKbQAoG34V_cQk7vxSA&confirm=yes'
Hi Mr. Andrzej
Thank you for replying my message. I changed the url file to the one you provided. But I am getting the following error:
