Can you please show me the command you ran and the full stack trace it gives you?

Sure. I ran python -m pip install --upgrade pytorch and the full trace is:

I tried deleting the cached version and doing a fresh download. That didn't work either.

since pytorch is not on PyPI yet, doing pip install --upgrade pytorch will not work.
You need to install a new wheel / conda binary with the commands from the website pytorch.org

When I use the command pip3 install torch
I also got the same warning

ImportError: No module named 'tools.setup_helpers'

Thanks,

as i mentioned above, pip3 install torch will not work.

I have a similar problem. I follow the instructions on installing pytorch on Linux via pip, python 3.5. The two commands in the instructions are as follows:

pip install https://s3.amazonaws.com/pytorch/whl/cu80/torch-0.1.9.post2-cp35-cp35m-linux_x86_64.whl pip install torchvision

The first (installation of the wheel) was fine. The second gave the ImportError: No module named 'tools.setup_helpers'. So I'm not sure this issue should be closed.

Here's the output:

Collecting torchvision
  Using cached torchvision-0.1.7-py2.py3-none-any.whl
Collecting numpy (from torchvision)
  Using cached numpy-1.12.0-cp35-cp35m-manylinux1_x86_64.whl
Collecting torch (from torchvision)
  Using cached torch-0.1.tar.gz
    Complete output from command python setup.py egg_info:

        from tools.setup_helpers.env import check_env_flag
    ImportError: No module named 'tools.setup_helpers'```

@svohara for some reason it's trying to reinstall torch from pypi. I have no idea why it's trying to do that, considering you already installed torch via the wheel. What is the version of pip that you are using?

What's the output of the command:
pip --version?

@svohara try using three backticks for quoting instead of one. That's hard to read.

Using cached torch-0.1.tar.gz 

Try finding and deleting that file.

same error message for
pip install pytorch

I'm using mac and python 3.5

@unnir pip install pytorch is not a valid or good thing to do. Where did you find that command?

@soumith I expect people will just keep doing this until there's a working package on PyPI. That's just the first thing people are going to try for a Python project.

Maybe you could upload an 0.2 wheel that just prints a more helpful error like:

Installation from PyPI not supported yet (see status at https://github.com/pytorch/pytorch/issues/566). For now, please uninstall this package (pip uninstall pytorch) and follow the instructions at http://pytorch.org/ to install with miniconda.

@soumith from the same place as I got a common sense.

normally I'm using pip for installing packages.

@lukeyeager totally agree.

@unnir i didn't mean you dont have common sense. Sorry about that.
@lukeyeager ok i'll try to get to that.

Install by pytorch.org
Not use pipy website for install
Surely it will done

I did't fix my problem. I'm trying to install Caffe2 for python (3.8.7). It shows me this message:
