❓ Questions and Help

I follow the INSTALL.md, but got a problem at last step like:

my environment is:

• ubuntu 18.04 LST, no gpu
• gcc version is 7.3.0
• pytorch-nightly-cpu installed, version: 1.0.0.dev20181113

Thank you!

It seems that which g++ is failing in your machine, can you try it locally?

which g++

Also, could you please copy and paste the output from the
environment collection script from PyTorch
(or fill out the checklist below manually).

You can get the script and run it with:

wget https://raw.githubusercontent.com/pytorch/pytorch/master/torch/utils/collect_env.py
# For security purposes, please check the contents of collect_env.py before running it.
python collect_env.py

• PyTorch Version (e.g., 1.0):
• OS (e.g., Linux):
• How you installed PyTorch (conda, pip, source):
• Build command you used (if compiling from source):
• Python version:
• CUDA/cuDNN version:
• GPU models and configuration:
• Any other relevant information:

@fmassa maybe just no g++. After I ran sudo apt-get install g++, I can ran setup.py.
Thanks for you remind.
