WARNING: Ipopt finished with status Invalid_Number_Detected - optimization

Trying to solve a large NLP. the code is approximately as follows:
using JuMP
using Ipopt
m=Model(solver=IpoptSolver())
#variable(m,k,start=1.2)
....
#NLparameter(m,α==0.28)
.....
#NLconstraint(m,cons1, 0<=((6.376151933328191*θ_1k^2*θ_3c -....<=0)
......
#NLobjective(m,Max,1.0)
solve(m)
With the first set of start values (some negative and other positive) for the variables, I receive the following error message:
WARNING: Ipopt finished with status Invalid_Number_Detected
When I alter the values of initials (all positive), I receive the following message instead
Warning: Cutting back alpha due to evaluation error.
Please, what could be the meaning of such behavior? Is there an Ipopt option that could help to solve the problem? Thanks for helping

GNURadio Companion and OFDM TX and RX in single Graph

I am following this github example for understanding OFDM on gnuradio-companion, I am able to execute ofdm_tx individually (64 and 512 FFT point) without any issues, but when I connect these two in single graph, I am able to get spectrum from ofdm_tx (no output from ofdm_rx or getting straight line).
My question here, each time I close my output spectrum, my tool get hanged and in background (inside gnu-companion) I observe the following message tarin (attached, printscreen). Similar thing also observed when I run ofdm_rx individually.
Error message in Console :
packet_headerparser_b :info: Detected an invalid packet at item 1448.
header_payload_demux :info :parser returned #f
Please guide me in this regard,
by selecting "NO" for vector source "Repeat" variable , issue sorted out (no hang), but not able to see spectrum anymore.

Subtracting Values from Two Datasets in Single Table

I'm trying to basically subtract time to get the time difference in SSRS to take out total working hours. However, I'm getting error "An unexpected error occurred while compiling expressions. Native compiler return value: '[BC30025] Property missing 'End Property'.'." from the available solutions in here or over the internet.
I tried to use lookup as well: =Lookup(Fields!Date.Value & Fields!Employee_Name.Value, Fields!Date.Value & Fields!Name_or_title.Value, Fields!Check_Out_Time.Value, "DataSet2") - (Fields!Check_In_Time.Value) which shows error as enter image description here
Can someone guide me how to get time difference from two different datasets please? I'm new to SSRSSQL

How to Clear SSIS Warning Code DTS_W_MAXIMUMERRORCOUNTREACHED?

I got this error message after running my SSIS package.
Source : flat text file
Target : sql database
Warning: 0x80019002 at Package: SSIS Warning Code DTS_W_MAXIMUMERRORCOUNTREACHED. The Execution method succeeded, but the number of errors raised (3) reached the maximum allowed (1); resulting in failure. This occurs when the number of errors reaches the number specified in MaximumErrorCount. Change the MaximumErrorCount or fix the errors.

Please help me on this .
In case of error means some issue is there and you need to fix it. But, still if you want to set the number to higher value, you can set at the package level.

Using Optaplanner for VRPPD

I am trying to run the example "optaplanner-mixedvrp-experiment" developed by Geoffrey De Smet and when I run it it throws me the following error:
Caused by: java.lang.IllegalStateException: The entity (MY) has a
variable (previousStandstill) with value (MUNO) which has a
sourceVariableName variable (nextVisit) with a value (WERBOMONT) which
is not null. Verify the consistency of your input problem for that
sourceVariableName variable.
I have not made any change, I have only cloned and executed it, I import and solve it and it throws me this error.
Do you know what could be happening?
I am applying it in the development of a variant of VRP with multiple deliveries and collections, but it throws me the same error. I have activated the FULL_ASSERT mode and nextVisit, previousStandstill, visitIndex are always null
It's been a long time since I looked at that code, so it's using an old version of optaplanner. Our goal is still to clean it up and offer an out of the box example for VRPPD (and probably remove some boilerplate along the way, using the upcoming #CollectionPlanningVariabe etc). That being said, we have multiple users&customers who used that optaplanner-mixedvrp-experiment to successfully build VRPPD implementations.
Which dataset did you try?
FWIW, that IllegalStateException says that when A.previous = B, the B.next is not A. So either the dataset importer didn't import it correctly - before calling solve() - especially if it fails before the first CH step in FULL_ASSERT. Or one of the custom moves corrupted the model.

vkMapMemory validation error on vkQueuePresentKHR, but never called the function directly

When calling vkQueuePresentKHR i get the following validation error:
Validation Error: [ VUID-vkMapMemory-size-00680 ] Object 0: handle = 0x8483000000000025, type = VK_OBJECT_TYPE_DEVICE_MEMORY; | MessageID = 0xff4787ab | VkMapMemory: Attempting to map memory range of size zero The Vulkan spec states: If size is not equal to VK_WHOLE_SIZE, size must be greater than 0 (https://vulkan.lunarg.com/doc/view/1.2.148.0/windows/1.2-extensions/vkspec.html#VUID-vkMapMemory-size-00680)
I never called vkMapMemory() directly.
Here is an excerpt of my code: https://gist.github.com/alexandru-cazacu/7847161564daa5f93d1bada39280faa8
Closing RivaTuner Statistics Server fixed the issue.
I had 3 other validation errors caused by it.
As stated in https://vulkan-tutorial.com/FAQ
I get an access violation error in the core validation layer: Make sure that MSI Afterburner / RivaTuner Statistics Server is not
running, because it has some compatibility problems with Vulkan.
