issue: Solving environment: failed

[momonala]

I get the following error. I can install pytorch on the smaller test environment fine, but when I try to install it outside of the test env. I get the following error. I tried downgrading from Python 3.6.3 to 3.6.0 to no avail. Additionally, if I uninstall for the package that conda questions, I just get the same error with a new package (ex. I uninstalled xeus but qt now appeared. Any suggestions?

Solving environment: failed

UnsatisfiableError: The following specifications were found to be in conflict:
  - pytorch
  - qt -> icu=58 -> *[track_features=vc14]
  - qt -> icu=58 -> vc==14
Use "conda info <package>" to see the dependencies for each package.

@momonala If you want to do this, please install the offline package.

[peterjc123]

@momonala It should be listed here.

[momonala]

This worked. Thanks!

[aaryansingh-dev]

@momonala It should be listed here.

I downloaded the required version of pytorch but have no idea where to paste the extracted files.

@aaryan1210 What is the error at your side?

[peterjc123]

@aaryan1210 Consider using the official one? The one in my repo is outdated.

[aaryansingh-dev]

`(base) C:\Users\HP>conda install -c peterjc123 pytorch-cpu

Collecting package metadata (current_repodata.json): done

Solving environment: failed with initial frozen solve. Retrying with flexible solve.

Solving environment: failed with repodata from current_repodata.json, will retry with next repodata source.

This is the error shown in anaconda prompt.

@aaryan1210 Please try conda install -c pytorch pytorch cpuonly.

[aaryansingh-dev]

I have a Cuda 9.2 toolkit installed and I downgraded my python version to 3.5 to match the version shown in error.

[aaryansingh-dev]

@aaryan1210 Please try conda install -c pytorch pytorch cpuonly.
Thanks a lot, this worked.

[aaryansingh-dev]

@aaryan1210 Please try conda install -c pytorch pytorch cpuonly.

Hey, I installed PyTorch using the above-mentioned code, but today the prompt is showing that no module named torch exists.

import torch Traceback (most recent call last): File "<stdin>", line 1, in <module> ModuleNotFoundError: No module named 'torch'

[peterjc123]

@aaryan1210 You have multiple python installation? What is the result of the following commands?

where conda
where python

[aaryansingh-dev]

Yes, I have 2 python installations and 3 conda installations.

F:\ProgramFiles\Anaconda3\Library\bin\conda.bat
F:\ProgramFiles\Anaconda3\Scripts\conda.exe
F:\ProgramFiles\Anaconda3\condabin\conda.bat

And python

F:\ProgramFiles\Anaconda3\python.exe
C:\Users\HP\AppData\Local\Microsoft\WindowsApps\python.exe

[peterjc123]

@aaryan1210 There is nothing wrong there. Maybe you installed it into a virtual environment?

[peterjc123]

Could you please show me the result of conda info -e?

[aaryansingh-dev]

I installed with (base) and I tried installing it in a virtual environment. But installed it in (base) too.

[aaryansingh-dev]

base * F:\ProgramFiles\Anaconda3
myenv F:\ProgramFiles\Anaconda3\envs\myenv

[peterjc123]

What about conda list pytorch and pip show torch?

[aaryansingh-dev]

# packages in environment at F:\ProgramFiles\Anaconda3:
#
# Name Version Build Channel

And pip didn't show any result.

[aaryansingh-dev]

I think think this means no pytorch is installed.

[peterjc123]

So it seems pytorch is not installed in this env. Just try to install it again.

[aaryansingh-dev]

Should I download it in env or base?

[peterjc123]

@aaryan1210 Just according to your needs. Both should work.

[aaryansingh-dev]

Ok, installation in env is working properly but the base* is showing error.

[peterjc123]

What error is it?
