Hi, sorry, for waking up this pretty old message but the solution you suggested seems to have some problem. The deserialization indeed gives me the following error: File "/home/lello/anaconda3/lib/python3.7/site-packages/tt/core/vector.py", line...

Thanks, I had an old version of the code without the permute function which seems to do exactly what I need. Since I am using a locally modified version of...

Thanks again. BTW, the modification I added to avoid problems in svd might also be of help. It is a very naive rescaling of the R matrix in the QR...

@rakhuba since you mentioned it, what would be the best way to permute indices for the identity matrix? I just realized that I the matrix I am trying to reshape/permute...

Indeed that reshape has full rank. Once I realized it I reformulated my entire problem to avoid the reshape/permute operations. Thanks for the hints.

I have found a much simpler example which shows the problem. The problem is in the dtt_ort() routine. The first element of the U matrix keeps growing and after a...

After looking at the methodology and at the code I don't believe that this is an error. When sweeping through the cores using the QR decomposition the R factor keeps...

The same problem holds in the SVD procedure. In this case the truncated singular value matrices of each core are multiplied K times running into overflow for very large K....
