how to install pytorch in python2.7?
Solution 1
Here's the link to the PyTorch official download page
From here, you can choose the python version (2.7) and CUDA (None) and other relevant details based on your environment and OS.

Solution 2
It seems that pytorch try to install some packages which requires python >= 3.6 version.
Package wheel conflicts for:
python=2.7 -> pip -> wheel
pytorch-cpu -> python[version='>=3.6,<3.7.0a0'] -> pip -> wheel
You have to specify in command for which python version would you like to install pytorch
Solution 3
For me the method in the link https://www.learnopencv.com/installing-deep-learning-frameworks-on-ubuntu-with-cuda-support/ worked.
This is how I did it:
!pip install http://download.pytorch.org/whl/cu80/torch-0.2.0.post3-cp27-cp27mu-manylinux1_x86_64.whl
Solution 4
First install conda with python2.7:
conda install pytorch torchvision torchaudio cpuonly -c pytorch
Then activate environment:
conda activate python2
Then install pytorch:
conda install pytorch torchvision torchaudio cpuonly -c pytorch
Check for confirmation:
python
import torch
print(torch._ _version_ _)

i am using python2.7 in virtual environment. i tried to install pytorch in python2.7 but i got error belows:
UnsatisfiableError: The following specifications were found to be incompatible with the existing python installation in your environment: - pytorch-cpu -> python[version='3.5.*|3.6.*'] - pytorch-cpu -> python[version='>=3.5,<3.6.0a0|>=3.6,<3.7.0a0|>=3.7,<3.8.0a0'] If python is on the left-most side of the chain, that's the version you've asked for. When python appears to the right, that indicates that the thing on the left is somehow not available for the python version you are constrained to. Your current python version is (python=2.7). Note that conda will not change your python version to a different minor version unless you explicitly specify that.

i tried conda install pytorch-cpu -c pytorch and link(https://pytorch.org/get-started/locally/). but it is not worked. so what should i do for install torch in python version2.7? i want to install pytorch cpu version.
plz help:)

anirudh about 4 yearsBoth for pytorch and and generally for machine learning you would be better off installing python 3 in a virtual environment

mimi about 4 yearsso, you mean i should specify pytorch version for python2.7?

Ishinomori about 4 yearsWhat os are you using? Note that PyTorch does not support Python 2.7 on Windows.

mimi about 4 yearsI use windows. OMG! can't i use torch in python2.7 on Windows?:(
