Hub: Failed to download model

[mohamedaashraf]

From couple hours ago, I tried to download a new model to make classification... but it gave me this message
`

I tried to download an existed model to test the problem, but it gives me the same error!
Any help ??
Note :I tried the image modules links on another PC and Internet connection... The links are not responding!
could anyone try to test the module download process, which have been done by Retrain.py code ?

[akhorlin]

Let us know a bit more info about the environment you are running (py, os versions, are you running on corp network that may have restricted access to some external sites), and the code in question.

[mohamedaashraf]

I'm running on ubuntu, Python codes
And this is my home network, so there is no restricted access there

[mohamedaashraf]

And I'm using the same retrain.py code from this repo

[akhorlin]

Could you please provide an output of "wget '
https://tfhub.dev/google/nnlm-en-dim128/1?tf-hub-format=compressed' -O
/tmp/module.tar.gz" command? This way we can determine whether the module
can be downloaded outside of the library or not.

[mohamedaashraf]

It's downloading tar file with size more than 400 MB

[mohamedaashraf]

I will close this issue, since I have found the solution..
I exchanged the download link
https://tfhub.dev/google/imagenet/inception_resnet_v2/classification/1
with
https://storage.googleapis.com/tensorflow-hub/google/imagenet/inception_resnet_v2/classification/1.tar.gz
and now, the download works!

[hansanjie]

it does not work anymore. I can not download Tf_mode from any of two directories .otherwith, I want download Inception V3 mode, does anyone know the new directory?

im having the same issue

[JIAZHEN]

I have the same issue even after I ran Install Certificates.command. Can you please reopen this issue and have a look?

[andresusanopinto]

Please see discussion in #97.

It appears many have installed software that takes control over ".dev" domain. TensorFlow Hub library then fails to reach the proper server (either with an SSL issue or other obscure error).

Users are highly recomended to switch off their ".dev" hijacking into ".test" [reserved for that purposed], since the ".dev" is nowadays a gTLD.

[andresusanopinto]

If you believe your issue is not due to ".dev", please create a new issue with an error output of running:

$ wget 'https://tfhub.dev/google/nnlm-en-dim128/1?tf-hub-format=compressed' -O /tmp/module.tar.gz

Avoid fallback to links such as "https://storage.googleapis.com/...", as those may break at anytime with no warning. The only stable url for modules hosted in tfhub.dev are the "https://tfhub.dev/" ones.

[TanLingxiao]

You can download your the model need from url + '?tf-hub-format=compressed', such as 'https://tfhub.dev/google/imagenet/pnasnet_large/classification/2?tf-hub-format=compressed' . This file will be named 'x.tar.gz', then make two file in ‘/tmp/tfhub_modules’ named such as '67f40766542914aa2dd2ec6923c4f353f6d0663c' and '67f40766542914aa2dd2ec6923c4f353f6d0663c.descriptor.txt' ,decompression 1.tar.gz to 67f40766542914aa2dd2ec6923c4f353f6d0663c.

[sivakotich]

Same issue is observed with python 2.7 also(error mentioned by andreyc0d3r. Any working solutions?

wget 'https://tfhub.dev/google/nnlm-en-dim128/1?tf-hub-format=compressed' -O /tmp/module.tar.gz works fine without any issue

[xieximing]

I seem have the similar issue for downloading the module. After I imported theimport tensorflow_hub as hub then I tried to download a fast-RCNN Module through detector=hub.Module("https://tfhub.dev/google/faster_rcnn/openimages_v4/inception_resnet_v2/1" ) but I got this feedback:

[arnoegw]

xieximing, you also filed that as https://github.com/tensorflow/hub/issues/169. I will respond there.

[perveil]

embed = hub.Module("https://storage.googleapis.com/tfhub-modules/google/Wiki-words-500-with-normalization")

i had read above comments and make some improvements, but my request don`t have any reponse

[arnoegw]

The module handles for use with hub.Module, hub.resolve, etc. can either be a filesystem path or the URL of a web service following tensorflow.org/hub/hosting#protocol. Please try https://tfhub.dev/google/Wiki-words-500-with-normalization/1 instead.

@andresusanopinto
Thanks for your reply. I'm also facing this issue. Could you elaborate on this hijacking issue? How could I find out what's responsible for this?
