How to print out LazyEvaluatedKernelTensor

[VhaoYan]

Hi, I have defined a scaleKernel which returns a covariance tensor as type LazyEvaluatedKernelTensor. I was wondering if there is a way that I can print out this matrix? I looked through the code but cannot find anything (maybe I miss it). Thank you so much!!

You can use to_dense() to make it into a standard tensor.

I guess this is technically a gpytorch discussion not a linear_operator one.

Thank you for replying.

But somehow the "pip install linear_operator" is not working. I checked from PyPI https://pypi.org/project/linear-operator/ which states "linear-operator" not "linear_operator", but still can not be installed from google colab

linear_operator requires python 3.8 or newer, and I believe the standard colab env uses python 3.7.

There may be some way to upgrade the python version in a colab session, but I'm not sure about that.
