QUESTION
We are using Mosek solver via its Cvxpy interface.
We deal with large-scale optimization problem on a regular-basis and sometimes the runtime is very high. So, we specify a upper limit on runtime using Mosek's mosek.dparam.optimizer_max_time
parameter.
In those cases, the pain-point is that we get no solution.
Is it possible to get the suboptimal/best found solution so far?
...ANSWER
Answered 2022-Feb-24 at 07:24If Mosek did not find any feasible integer solution within the time limit then there is nothing to return, so you get nothing.
If Mosek found some feasible integer solution then CVXPY should return it with solution status s.OPTIMAL_INACCURATE, judging from a quick look at the code.
So the question is what does it say in the log output and what happens at the end of the optimization when CVXPY is processing the answer from the solver.

QUESTION
To start with, Mosek's initialization API works great. We were able to speedup our optimization by 25X, merely by decision variable initialization on a sample problem (all variables integral constrained).
Now, we are solving a new large-scale MIQCQP problem (with some variable integral constrained and some contiguous) and we want to initialize all those variables.
When using the task.putxxslice
API [1], we are facing issues in deciding the value of whichsol
parameter.
Doubts:
Since our problem has both integral and continuous, would it be correct to substitute
whichsol = mosek.soltype.itg
for all variables (integral and contiguous)?Our final objective is adding this generic support custom Cvxpy. We have almost achieved that, just that - Is there any a programmatic way to decide
whichsol
in Cvxpy? Or better asked - Is this the correct way?
ANSWER
Answered 2021-Sep-30 at 06:40The reasons to set an initial point in Mosek are:
Starting feasible point for the mixed-integer solver when the problem has integer variables, in that case set
itg
Warm-starting the simplex solver, in that case set
bas
.Warm-starting the conic/interior-point solver, in that case set
itr
, although this option is only theoretical because currently Mosek will not warm-start and just ignores that solution.
Normally if there are any integer variables in the problem, then only the itg
solution is relevant. If the problem is linear and the simplex solver is explicitly chosen via a Mosek parameter then only the bas
solution is relevant.
However imagine that the problem has integer variables but the user sets the Mosek parameter iparam.mio_mode=ignore
because then now want to solve only the LP relaxation. That is extremely unlikely that someone seriously needs such a combination but at least in principle it is possible. What then? There are lots of corner cases like this, and you would have to explicitly check lots of Mosek parameters (which can change over time) to make a decision.
One way out of this is to set all three primal solutions, and also set the parameter iparam.remove_unused_solutions
. Then, once Mosek internally decides which optimizer will be used, it will purge those solutions which are not relevant at this point.
Another option is that you only set the itg
solution. It is very unlikely that any cvxpy users would use this feature for anything else than 1. above.

QUESTION
In below code snippet I am trying to do a very simple linear regression using cvxpy and mosek solver
...ANSWER
Answered 2021-Sep-10 at 19:25it's hard to answer this question without having a reproducible example with your data.
Your python code seems fine, so I believe the problem is in your data: if I must take a guess, I assume you have NaNs
somewhere in your data which causes the failure.
I'm not sure if cvxpy and mosek handle nans at all, so it's a good idea to verify your data integrity before using them.

I am a newbie to deep learning so while I am trying to build a Masked R-CNN model for training my Custom Dataset I am getting an error which reads:
...ANSWER
Answered 2020-Dec-21 at 11:52I got this error when upgrading from tensorflow 1.2.1 to 2.4. It appears the statement "x, K.shape(input_image)[1:3]))(input_gt_boxes)" is causing the bug. This is possibly due to an API change in tensorflow and/or Keras. I suspect the code you're trying to run is made for a different version of tensorflow than the one you got installed. You could try to install a matching version of tensorflow and keras or you can try to fix the code to comply with your current version. In my case I had to make slight changes to the way I constructed the model, but it is not easy to see how that can be done for your case without downloading the model library.

QUESTION
Based on LightGBM's documentation in the link below, the parameter categorical_feature
(for categorical features) states that "All negative values in categorical features will be treated as missing values."
My question is: Are the negative values (ie. missing values) in categorical features treated as a separate category? Or are they just treated as missing values and are not included as a category in the model?
Many thanks in advance.
...ANSWER
Answered 2020-Oct-12 at 13:14Either way :) the nans will be grouped in a way that minimizes error, not discarded

Install PythonAPI
You can use PythonAPI like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
