There's a CI workflow that tests building the image, can you update it as well ?

If this Dockerfile in the is specificially for IPEX, should it be renamed to Dockerfile.ipex, to not confuse users?

[kaixuanliu]

@helena-intel ,Hi, this Dockerfile is just used for CI test, but I think your advice is OK. Have renamed it to Dockerfile.ipex

[IlyasMoutawwakil]

Hi ! I aslo think having separate Docker files is better. The build test is failing tho

Seems there is sth wrong with access to machine putting release wheel files. Have replaced --extra-index-url from https://pytorch-extension.intel.com/release-whl/stable/cpu/us/ to https://pytorch-extension.intel.com/release-whl/stable/cpu/cn/ temporarily
