QUESTION
To give more context about my problem:
I am using python to build an API connecting to the TWS of interactive brokers. I managed to build something functional and able to fetch live data from contracts using the methods given in the doc of IB. Now that I want to use all the data to build other parallel systems with it, I have encounter problems organising the data that arrives from the IB server.
My program loops a list of 30 symbols to get live data from and then I want to put the data (ex. 'HIGH', 'LOW', 'CLOSE', 'VWAP' etc) from each symbol all together in one dataframe to calculate indicators and from there come up with an alert system that is based on them indicators.
This objective I have already accomplished it using only one symbol for the whole program. Is easy to store the data in instances or variables, pass it to a DataFrame and then calculate to set up alerts.
Now when looping a list of 30 values and receiving the data of all of them I have struggled trying to store the data for each symbol together and then calculate and set up alerts. Specially when I have to use several methods to receive the data (ex. I use tickPrice for some data and tickString for some other data) this several methods execute themselves one after the other but they wont necessarily have all the data at the same time, some values take more time than others to show.
I will show an example of my code to give even more context of my objective:

QUESTION
I have Azure Bot deployed with Virtual Assistant Template, which was working fine (And still working in Portal's Test In Web Chat feature) until I enabled Direct Line App Service Extension.
Primary objective to enable DL App Service extension is to isolate bot access and secure app service.
I have followed MS documentation https://docs.microsoft.com/en-us/azure/bot-service/bot-service-channel-directline-extension-net-bot?view=azure-bot-service-4.0 and ensured every step is configured correctly.
Primary step to make sure DL app service is working correctly is to check if https://xxx.azurewebsites.net/api/messages or https://xxx.azurewebsites.net/.bot/ url return correct json result f.x: {"v":"123","k":true,"ib":true,"ob":true,"initialized":true} But instead i am getting Error Response 400 Bad Request and error message appeared in browser is : "Upgrade to WebSocket is required."
I couldn't even reach to a step where troubleshooting guide mentioned here : https://docs.microsoft.com/en-us/azure/bot-service/bot-service-channel-directline-extension-net-bot?view=azure-bot-service-4.0#troubleshooting could help to resolve.
As i said earlier Bot is still working and the url : https://xxx.azurewebsites.net loads site correctly , can be seen in below
Any help is appreciated

QUESTION
I am trying to ingest data from kafka into aerospike. What am I missing in the kafka message being sent?
I am sending below data into kafka for pushing into aerospike:
...ANSWER
Answered 2022-Jan-19 at 03:20It looks like you are not specifying a key when you are sending your kafka message. By default Kafka sends a null key and your config says to use the kafka key as the aerospike key. In order to send a kafka key you need to set parse.key to true and specify what your separator will be (in the kafka producer).
see step 8 here

ANSWER
Answered 2022-Jan-14 at 16:50First of all, it has nothing to do with np.random.RandomState()
, it works just the same with e.g. np.ones
. Note that if you use ellipsis ...
as part of the input shapes, the ellipsis will stand for the same (up to the rules of broadcasting) shape throughout the whole expression. In your case you try (slightly rewritten)
QUESTION
I have a dataframe with two column: PathGroupStage, ClinGroupStage. I want to create a new column, OutputStage, that chooses the higher stage.
Valid value of stage: I, IA, IB, II, IIA, IIB, III, IIIA, IIIB, IIIC ,IV, IVA, IVB, IVC, Unknown.
- If both stages have values, then use the highest, e.g., IIIB > IIIA > III
- If one is missing and the other has value, the use the one with value
- If both are missing or unknown, then .= unknown
How would I derive the OutputStage variable comparing the non-numeric values from the two columns? I am thinking I need to factor levels but how would I compare the factors between different columns?
Here is the sample dataset:

I would like to structure and unstructure an attrs
object, which includes dict
fields that use simple frozen attrs for the dict keys. This works very well for objects created at runtime, but the frozen attribute fails to make un/structuring with cattrs easy.

...ANSWER
Answered 2021-Nov-11 at 23:37Well, you can always use marshmallow for stuff like this. It allows you to fully customize the process via schemas. It is usually a good idea to keep your serialization/deserialization separate from your business logic anyway. So, for your example it could look something like this:
QUESTION
I'm generating dynamically table N columns x M rows
and I'm trying to make it print with default printing options as good as possible
So,
Whenever we're printing the table on A1/A2/A3/A4 paper, then table should TRY to occup full one piece of paper, its avaliable space with as biggest font as possible (people who will read it may not have perfect eyesight)
But when I go to e.g Microsoft Edge (it has tools to manipulate scaling, margins and stuff, so that's why I used it, which kinda worries me too, that printing results on Chrome/FF/Edge may vary)
and use preview (CTRL+P), then it always either takes more than one page, or uses only e.g 40% of avaliable space
