Referring to https://github.com/NVIDIA/tensorflow#install is what originally got me to this point, so... Not sure what to do next. Any help?

$ pip --version
pip 20.1.1

[DEKHTIARJonathan]

I'm pretty sure the error comes from Anaconda. Can you try the following for me:

pip install --extra-index-url=https://pypi.ngc.nvidia.com --trusted-host pypi.ngc.nvidia.com nvidia-tensorflow

The objective of the package you try nvidia-pyindex and that fails, install the nvidia python package repository to avoid having to write this complex command.
So if it doesn't work, you can go around it like that.

If you are using a docker container, can you please send me the docker container name ? I'd like to be able to reproduce it. Thanks

[drscotthawley]

Thanks for your reply. Looks like I get the same error message:

I'm able to install other packages via conda's pip, just not this package.

I tried deactivating the conda environment and starting a clean virtualenv environment, but am having other, more general, problems with pip supplied in the venv.

[DEKHTIARJonathan]

EDIT: I just realized you are using Python 3.7. We don't support that.
Only Python3.8 from the December release, and Python 3.6 for November and before

So everything is actually normal. PIP complains he can't find a candidate to install because None exists.

[drscotthawley]

Oh.. thanks, wish I'd read this sooner. I just finished installing Python 3.7 so I could avoid conda and get venv+pip working! LOL. Will try 3.8 instead now.

[drscotthawley]

Ok problem now resolved. Had a couple issues along the way that I will post here for future users who may have similar issues:

With python 3.8 & venv/pip I was getting a different error.

$ python3.8 -m venv env_spnet
$ source env_spnet/bin/activate
(env_spnet) $ pip install --user nvidia-pyindex
Exception:
Traceback (most recent call last):
  File "/home/shawley/env_spnet/lib/python3.8/site-packages/pip/basecommand.py", line 215, in main

  File "/usr/lib/python3.8/posixpath.py", line 76, in join
    a = os.fspath(a)
TypeError: expected str, bytes or os.PathLike object, not in

The problem here was that the pip installed by default on Ubuntu is ancient (v9.0). But if you bootstrap pip via

curl https://bootstrap.pypa.io/get-pip.py | python3.8 -

Then you can run the install commands, albeit without the --user part.

After that, installation proceeds without errors. Closing this issue.

[mahdaneh]

Hi,
thanks for allowing us to know that nvidia-tensorflow is only working with python3.8. Save my time a lot .
Following this instruction , I did not see that requirement in the webpage. I would suggest that maybe the webpage can indicate this in the pre-requirement section.

[mrjoness]

Hello,

I am seeing this same issue but neither python 3.8 nor the --extra-index flag seems to fix the problem. The pyindex command worked with no issues. Here is my current conda list for reference:

I have the same issue under Ubuntu 22.04.1 LTS with Python 3.10.6

Trying:

pip install nvidia-pyindex
pip install nvidia-tensorflow[horovod]

or

pip install --extra-index-url=https://pypi.ngc.nvidia.com --trusted-host pypi.ngc.nvidia.com nvidia-tensorflow

Both return the error previously shown which advises the package is a pypi.org placeholder and to see the install instructions.

EDIT: I notice that https://pypi.org/simple returns HTML that appears to be a list of packages, whereas https://pypi.ngc.nvidia.com redirects to https://developer.download.nvidia.com/compute/redist/ (which is a blank page)

I'm unsure whether the pypi.org HTML is there simply for the benefit of humans, or that's the actual index data that pip uses. If it's the latter, that may explain why pip cannot find nvidia-tensorflow on pypi.ngc.nvidia.com.

Facing the exact same issue. Any luck getting it to work?

[rmc135]

My apologies, I forgot to follow this up.

https://developer.download.nvidia.com/compute/redist/nvidia-tensorflow/ shows the list of WHL files.

Based on those filenames, it seems that "Only Python3.8" from an earlier reply is probably meant to be taken literally? :) ie, no support for 3.9 or later.

I set up a virtual environment with Python 3.8.15 and was able to install nvidia-tensorflow 1.15.5+nv22.11
