model links data.dmlc.ml are broken

[jnorwood]

The model links referencing data.dmlc.ml in the model zoo and inference examples are broken.
To fix this, it appears there are more than one issue. First, there are no longer gzipp'd files, and second the data.dmlc.ml site is no longer the correct source for wget.

so, this works:

wget http://data.mxnet.io/models/imagenet/resnet/18-layers/resnet-18-symbol.json

and this works:

wget http://data.mxnet.io/models/imagenet/resnet/18-layers/resnet-18-0000.params

and this works:

wget https://github.com/dmlc/web-data/raw/master/mxnet/neural-style/model/vgg19.params

but the links on https://mxnet.apache.org/model_zoo/index.html

for models and param files are of the form
http://data.dmlc.ml/models/imagenet/squeezenet/squeezenet_v1.1-symbol.json

and the tgz download doc in https://github.com/dmlc/mxnet-model-gallery/blob/master/imagenet-1k-vgg.md uses
wget http://data.dmlc.ml/mxnet/models/imagenet/vgg/vgg16.tar.gz

and that is true for the other models under https://github.com/dmlc/mxnet-model-gallery

So, basically, just look through all the docs and examples and change data.dmlc.ml to whatever is supposed to be the correct address for the downloads. It isn't evident to me if it should be coming from the github raw link above or the data.mxnet.io links, but data.dmlc.ml is simply broken.

Hey, this is the MXNet Label Bot.
Thank you for submitting the issue! I will try and suggest some labels so that the appropriate MXNet community members can help resolve it.
Here are my recommended labels: Bug, Doc

According to https://lists.apache.org/thread.html/129d8cb92a978d59ac7dd038c86ffb2db82dc708a3bc09da23727072@%3Cdev.mxnet.apache.org%3E, the change should be data.dmlc.ml => data.mxnet.io

@mxnet-label-bot add [Doc, Example, Good first Issue, Call for Contribution]

My pr also crashed by that: #14474

[jnorwood]

Let me add that the mxnet/cpp-package/example/inference/unit_test_inception_inference.sh is also has the line
wget -nc http://data.dmlc.ml/mxnet/models/imagenet/inception-bn.tar.gz
so I presume it is also broken.
That probably needs to be separated to three commands, one for .json and one for .params files, and one for the synset.txt. The data.dmlc.ml needs to change to data.mxnet.io

[jnorwood]

i got that unit_test_inception_inference.sh test to work with the following changes
wget -nc -O model/Inception-BN-symbol.json http://data.mxnet.io/mxnet/models/imagenet/inception-bn/Inception-BN-symbol.json wget -nc -O model/synset.txt http://data.mxnet.io/mxnet/models/imagenet/synset.txt wget -nc -O model/Inception-BN-0126.params http://data.mxnet.io/mxnet/models/imagenet/inception-bn/Inception-BN-0126.params?raw=true
plus ,remove the tar line

I'm working on the fixes here: #14504

[lanking520]

Now fixed are applied. @jnorwood please feel free to verify and close this issue.

Now fixed are applied. @jnorwood please feel free to verify and close this issue.
Thanks for fixing those. I still found references to data.dmlc.ml in the following files.

docs/model_zoo/index.md

example/rcnn/README.md

tools/coreml/README.md

tools/coreml/test/test_mxnet_models.py

The http://data.dmlc.io/mxnet/models/imagenet/vgg/vgg16.tar.gz link is returning a 403 error. It looks like you're using AWS but the .tar.gz file permissions are not set for public URLs. Can that URL (and the other model URLs) be updated?

Thank you!

[lebeg]

@jrosebr1 the link you provided is a bit confusing, it should be either http://data.dmlc.ml/... or http://data.mxnet.io/....

In any way check latest master that has #14504 merged. If you notice some other link failing let us now.

[jnorwood]

there are more broken links still referencing data.dmlc.ml. for example:
grep data.dmlc.ml */*/* 2>/dev/null
finds several in docs/model_zoo/index.md and a few others
and you can repeat this and find several more in deeper subdirectories.
grep data.dmlc.ml */*/*/* 2>/dev/null
finds a couple in tools/coreml/test/test_mxnet_models.py
That's all I can find that are remaing, related to this issue.

[jrosebr1]

@lebeg Sorry for my misunderstanding. What is the correct URL to download the VGGNet (trained on ImageNet) model?

[jnorwood]

http://data.mxnet.io/models/imagenet/vgg/vgg16-0000.params
http://data.mxnet.io/models/imagenet/vgg/vgg16-symbol.json

These above work, but the https://mxnet.apache.org/model_zoo/index.html is still not updated, else I would close this.

[jrosebr1]

Thanks @jnorwood!

I've updated the remaining http://data.dmlc.ml/ links that I found and verified them in #15065
