The error did not occur when running the training with the demo file video-1-PE-seq.npy
from vame.
Thank you, Kevin. After the extensive search and the discussion with you via email, I was able to solve that issue.
Apparantly, I forgot to align my data egocentrical which started a whole barrage of problems. I tried several different approaches to rule out any conversion issues but could not find any.
It is weird that a different set of numbers creates that issue, but my transformed data is working.
I want to write down a few things from my search that were weird:
The File-PE-seq.npy
file created by your demo code was structure the same, but was dtype object rather than float64.
I was able to create a training set with it which was dtype float64.
The content of the file was shaped like this:
[[546.5120849609375 545.6234741210939 544.8563232421875 ... 329.7113037109375 330.50433349609375 332.00457763671875], ...]
while the demo set only had rounded numbers like this:
[[150. 150. 150. ... 150. 150. 150.], ...]
Both are float and in the same range.
After transforming my original data, I ran in a totally new error that i will discuss in a seperate issue that is also connected to the values of the file. Very interesting!
Again, Thank you for the quick response.
I am still wondering what caused the error.

Hi Jens,
Again, thans for trying out VAME and reporting on issues you found in the code!
The error in the SVD solver probably happened because the use of un-aligned marker time series produces a Z matrix that is ill-conditioned, i.e. contains values spaning many orders of magnitude.
We think about adding a check on the condition number of Z in a future release of VAME in order to ensure exception handling prior to the solver call. Thanks for pointing this out.
Best,
Pavol
