Dali: cannot install dali HTTPError 404

[adrianstaniec]

I used this command:

pip3 install --user --extra-index-url https://developer.download.nvidia.com/compute/redist/cuda/10.0 nvidia-dali

I get this error:

requests.exceptions.HTTPError: 404 Client Error: Not Found for url: https://pypi.org/simple/nvidia-dali/

Also:
specifically it doesn't show up here:
https://pypi.org/simple/

also here:
https://developer.download.nvidia.com/compute/redist/nvidia-dali/
0.7.0 is the newest (I was expecting 0.8.0)

[adrianstaniec]

I tried this #1065 didn't help

[awolant]

Thanks for reporting the issue. I will look into what happens there.
In the meantime, I think you can find .whl files you are looking for with direct link

[awolant]

Since 0.8 release, we do not use https://developer.download.nvidia.com/compute/redist/nvidia-dali/, as we support two CUDA version.
We were never on https://pypi.org/simple/
Additionally to the link I provided before, you can look into releases page on the github https://github.com/NVIDIA/DALI/releases

1. wheel file

Ok i managed to install nvidia-dali from the wheel file (from your link)
but now I have problem installing the nvidia-dali-tf-plugin (from similar link).
Somehow the plugin installation still looks into pypi.org/simple which gives 404.

2. Official way

Why the method mentioned in the official documentation here doesn't work anymore?
I used to work fine in the past

[JanuszL]

I see some issue reported to pip that sound like one you faces. Can you check it?

[adrianstaniec]

As a workaround I unpacked nvidia-dali-tf-plugin-0.8.0.tar.gz
and removed nvidia-dali from install_requires argument from setup call in setup.py.
and than I coudl install the tf-plugin from new tar.gz file.

But anyway in the meantime something changed on the servers I guess,
I now I can again just install with the command recommended by documentation:

pip3 install --user --extra-index-url https://developer.download.nvidia.com/compute/redist/cuda/10.0 nvidia-dali
pip3 install --user --extra-index-url https://developer.download.nvidia.com/compute/redist/cuda/10.0 nvidia-dali-tf-plugin

[JanuszL]

Do you use any proxy? I think we haven't changed anything in our servers since then.
