There was a problem hiding this comment.
Is there a way to make this PR and #353 compatible?
|
Besides the scripts, we need a tutorial helping users to set up the environment. In my (limited) experience it is actually more frustrating than implementing the script. |
|
@hetong007 I agree. I have a quip doc draft for step-by-step training setup but I do not yet have the cycle to polish it for wider audience |
|
Then maybe we can at least provide a bash file and log for distributed training of resnet50 on imagenet. |
|
@eric-haibin-lin Will this still be up to date after the unified Dist api modification? apache/mxnet#17010 |
|
yes #17010 is backward compatible |
