Python implementation of the TT-Toolbox
`tt.optimize.tt_min.min_tens` does not work at least for `ttpy==1.2.1` How to reproduce: [example](https://github.com/oseledets/ttpy/blob/b440f6299a6338de4aea67f3d839d613f4ef1374/tt/optimize/example.py#L16) ``` import tt from tt.optimize import tt_min tens = tt.rand([3, 4, 5, 4, 3], 5, 3) min_element =...
ttones=tt.ones(10,400) tt_test=ttones*0. for i in range(50): tt_test=tt_test+ttones tt_test=tt_test.round(1e-3) print(tt_test.r[10]) It seems like tt.round is not really controlling the rank growth for the above example (d=400). If one uses, say, ttones=tt.ones(10,200)...
y=tt.rand(2,11,3); yr=tt.reshape(y,[2,2**10]); Error for ys=yr.round(1e-6) Error for print(yr[1,1])
Dear developer: I am a beginer in python. When I set up the toolbox of ttpy in Win10 by pip install and source code. a question appeared.That is error: f90...
Hi, I know this is probably not maintained anymore but in case some wants to use the TDVP algorithm please change the file ksl.py. The line y0 = y0.round(1e-14) changes...
Hi, it seems that the python interface for reading a vector/matrix in TT format from a file is missing but all the fortran subroutines are implemented. The write() interface is...
Do you have a python version of the function dot with CHUNK_START and CHUNK_END ? I see the version in python admits only 2 input arguments corresponding to TT1 and...
Hi, is the two-site version of the TDVP integrator planned? or what would be the best starting point for its implementation? Thanks, Raffaele
Hello, I've used the function 'drmg_cross.m' of TT-Toolbox package in Matlab, which inputs a function handle. Now I want to use the corresponding function in ttpy, so I installed this...
Tried to run ttpy on WSL today, ran into the following issue when running this trivial code: `tt.unit(2, 2)` ``` TypeError Traceback (most recent call last) in ----> 1 tt.unit(2,...
