You are not measuring the elapsed time correctly:

1. total_send_time measures the duration of the spawn() call, but as the actual task is executed asynchronously, start_in.elapsed() does not give you any information about how much time the task actually takes.

2. The ran in time, as measured by start.elapsed() is also not useful at all. As you are using blocking sleep operation, you are just measuring how much time your app has spent in the std::thread::sleep()

3. Last but not least, your time_to_sleep calculation is completely incorrect, because of the issue mentioned in point 1.

You can apply a function to the column that will make the item_id "uniform", then can drop_duplicates()

You can change the function to -

The curve_fit method doesn't support additional constraints. However, you could implement a non-linear least-squares problem

If you had broken down the code to isolate the problem you would get to:

For me, this is a natural fit for awk:

It's hard to tell from what you posted why you are getting an error, so I can only add some information that can hopefully allow you to troubleshoot the issue.

Your message has WS-Addressing headers, being one of them. The value of this field should be specified in the WSDL if your WSDL also includes WS-Addressing Metadata information, or should be specified in the documentation of the web service you are invoking. Your error message "XML Request is not well formed, Action does not exist" seems to indicate that there might be an issue with this field, but there is another action that SOAP services have which is a SOAP action. I asked about it in the comment above to make sure it's eliminated as a source of problems. In SOAP 1.1 it's called SOAPAction and is a separate HTTP header, while in SOAP 1.2 it's an action parameter on the HTTP Content-Type header. Based on the http://www.w3.org/2003/05/soap-envelope namespace, you have a SOAP 1.2 message.

With these explanations layed out, I suggest you take the WSDL and feed it to SoapUI who can generate sample requests that you can use to invoke the web service. If the WSDL also contains WS-Addressing Metadata, SoapUI should be able to pick it up and help you fill in the values you need. If not, look again through the WSDL for Action elements (make sure you differentiate between the SOAP Action and the WS-Addressing Action using their XML namespaces) or through the service documentation.

Once you get a succesfull call using SoapUI, then try to duplicate it with your code. At that point you can again use SoapUI to troubleshoot things and inspect your code built message to see it resembles the one you can successfully send with SoapUI.

Hope this helps get you closer to a resolution.

You should use the FutureBuilder widget to update your user interface when the data is available. The code you provided attempts to build the widgets before the data is received. This causes the _historyList to still be null.

In your problem you are trying to use Sequential API to create the Model. There are Limitations to Sequential API, you can just create a layer by layer model. It can't handle multiple inputs/outputs. It can't be used for Branching also.

Below is the text from Keras official website: https://keras.io/guides/functional_api/

The functional API makes it easy to manipulate multiple inputs and outputs. This cannot be handled with the Sequential API.

Also this stack link will be useful for you: Keras' Sequential vs Functional API for Multi-Task Learning Neural Network

Now you can create a Model using Functional API or Model Sub Classing.

In case of functional API Your Model will be

Assuming Output_1 is classification with 17 classes Output_2 is calssification with 2 classes and Output_3 is regression
