Installation error:zlib.error: Error -3 while decompressing data: invalid block type

Python 3.6.8
Ubuntu 18.04 on virtualbox 6.1.14
But kept giving me the error.

zlib.error: Error -3 while decompressing data: invalid block type

I’ve never encountered this error before. Could you update zlib or create a new virtual environment and reinstall PyTorch?
