Conda installation wants to downgrade to PyTorch 1.12.1
niphiwi opened this issue · comments
On a fresh conda environment with only PyTorch 2.1.2 cpuonly (and its dependencies installed), I want to install Pytorch Cluster.
conda install pytorch-cluster -c pyg throws me the following error:
conda install pytorch-cluster -c pyg
Channels:
- pyg
- defaults
- pytorch
Platform: win-64
Collecting package metadata (repodata.json): done
Solving environment: \ warning libmamba Added empty dependency for problem type SOLVER_RULE_UPDATE

The following packages are incompatible
├─ pin-1 is installable and it requires
│ └─ python 3.11.* , which can be installed;
└─ pytorch-cluster is not installable because there are no viable options
├─ pytorch-cluster 1.5.9 would require
│ └─ python_abi 3.6.* *_cp36m, which does not exist (perhaps a missing channel);
├─ pytorch-cluster 1.5.9 would require

├─ pytorch-cluster 1.5.9 would require

Pins seem to be involved in the conflict. Currently pinned specs:
- python 3.11.* (labeled as 'pin-1')
My understanding is that my problem is the incompatibility with Python 3.11. Therefore I downgrade to Python 3.10:
conda install python=3.10
Now, however, it tries to downgrade to PyTorch 1.12.1. Why is that? I was able to install PyTorch Cluster with Pip in the past, but what's the problem with conda that I am missing?
The following NEW packages will be INSTALLED:
cudatoolkit pkgs/main/win-64::cudatoolkit-11.3.1-h59b6b97_2
future pkgs/main/win-64::future-0.18.3-py310haa95532_0
pytorch-cluster pyg/win-64::pytorch-cluster-1.6.0-py310_torch_1.12.0_cu113
six pkgs/main/noarch::six-1.16.0-pyhd3eb1b0_1
The following packages will be DOWNGRADED:
intel-openmp 2023.1.0-h59b6b97_46320 --> 2021.4.0-haa95532_3556
mkl 2023.1.0-h6b88ed4_46358 --> 2021.4.0-haa95532_640
mkl-service 2.4.0-py310h2bbff1b_1 --> 2.4.0-py310h2bbff1b_0
mkl_fft 1.3.8-py310h2bbff1b_0 --> 1.3.1-py310ha0764ea_0
mkl_random 1.2.4-py310h59b6b97_0 --> 1.2.2-py310h4ed8f06_0

numpy-base 1.26.3-py310h65a83cf_0 --> 1.24.3-py310h3caf3d7_0
pytorch 2.1.0-cpu_py310hb0bdfb8_0 --> 1.12.1-cpu_py310h5e1f01c_1
torchaudio 2.1.0-py310_cpu --> 0.12.1-py310_cpu
We currently have trouble building conda wheels on Windows, that's why it is probably downgrading you to an earlier PyTorch version. Would installing from pip work for you for now?
Installing from pip is okay for me (and works). I was just curious about the behavior and did not find a related issue here.
But then it's probably related to the warning in the PyG documentation ("Conda packages are currently not available for Windows and M1/M2/M3 macs")?
Yes :(
