We can't do logdet() on GPU since it need MAGMA to do it on GPU.
We need to have magma in the official repository and build pytorch against it.

Currently we have to do logdet() on CPU.

Additional info:
* package version(s) python-pytorch-cuda 1.1.0-8
* config and/or log files etc.
* link to upstream bug report, if any

Steps to reproduce:

% python
Python 3.7.3 (default, Jun 24 2019, 04:54:02)
[GCC 9.1.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import torch
>>> torch.eye(512).div(500000).cuda().logdet()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
RuntimeError: lu: MAGMA library not found in compilation. Please rebuild with MAGMA.

Please test pytorch in [community-testing]. It should have magma enabled.
