Submission GuidelinesHello,
After used the new "Image Recognition Tool" a few days, I think you could improve it :
> by adding the dimensional constraints in front of each of the pre-trained models,
> by adding a true tool to divide the training data correctly (in order to have an equivalent number of images for each of the labels)
> at least, allow the tool to use black & white images (I wanted to test it on the MNIST, but the tool tells me that it necessarily needs RGB images) ?
Question : do you in the future allow the user to choose between CPU or GPU usage ?
In any case, thank you again for this new tool, it is certainly perfectible, but very simple to use, and I sincerely think that it will allow a greater number of people to understand the many use cases made possible thanks to image recognition.
Thank you again

Thank you again.

There are cases where a batch macro is used for multiple tasks where not all of the control parameter inputs are available all of the time. To use a batch macro control parameter it must be populated with a field, meaning sometimes a field containing a dummy value may have to be created to work-around this forced populating.
It would be useful if control parameter inputs could be made optional, passing a NULL value when a field hasn't been provided and handling any NULLs passed in within the batch macro.
In version 10.5 if the taskbar is auto-hidden and alteryx is the active window - you cannot access the taskbar by moving the mouse to the bottom of the screen.
You have to use the windows key or switch to another application window
I would love to see a detailed change log to help when I encounter issues after upgrading from one version to the next. For concrete examples, I've come across these issues recently:
1) Files saved to %TEMP% were displayed to the end user in the 10.0 but not 10.1 when running in the gallery.
2) The cross tab in 10.1 would run with a warning if you had column heading of "p_d" and "p d" where the space in the latter item is changed to a _ and then one of them is renamed with a 2 at the end ("p_d" and "p_d2"). In 10.5 you now get a warning and an error and the workflow stops. I've attached a sample workflow.
I'm all for bugs getting fixed and the improvements not always being backwards compatible, but I struggle with some of these when I can't reference a detailed change log. For some context, I've also attached a change log from some other software I used in a previous life. Anytime that a change in coding could affect past results, there was a note in the change log to identify these changes to the end user.
The ability to directly edit the XML for tools is fantastic.
Would love an edit option on the XML view for the workflow.
One slight issue on the tool one is that it doesnt run through the Config UI so the Annotation is not recomputed. Would be useful if the annotation was recomputed post XML edit.
Hi there,
Just a quick note on a really small improvement that could be made on the Data Cleansing tool but that could help a lot.
Actually this tool allows us to convert input data with NULLs to either blank or 0 values depending on the datatype.
It would be really appreciated to be able to do the opposite, converting blank or 0 values to NULLs.
Please add ablity to globally, within a module, forget all missing fields.
Please provide an option to have a the caption of a tool container sent to log/results after all items within it have been processed.
When you press tab from from the Test Type combo jumps to the Ok box, think should go to Test Value text box
It would make it a lot easier to create and manage a work stream if you added the standard ability to maximize and minimize the workflow canvas and configuration and results windows.
I understand that Server and Designer + Scheduler versions have the option to "cancel workflows running longer than X”.
I'd like to see that functionality in the desktop edition as well.
In the Formula Tool, there is an Average() function which can be used to take the average/mean of multiple columns or expressions. This function treats null values as zeroes. This was a surprise/dissapointment to me as I am used to other applications & systems where nulls are ignored, for example Excel. It would be useful to have either an AverageIgnoreNulls() function or an optional extra parameter to Average() which specifies that nulls should be ignored rather than treated as zeroes.
When wishing to average a small number of columns and ignore nulls, a formula can be constructed using Iif(IsNull([Column1]),0,[Column1]) for each column to calculate the total, and Iif(IsNull([Column1]),0,1) for calculating the count. This quickly becomes unwieldy for more than 2 or 3 columns.
It would be great if you could link a comment box to an object. This would be great because if the objects moves for what ever reason the comment would stay with it.
I think this is a product idea, but Alteryx doesn't look terrific on small 15" 4K screens (I have a Dell XPS 15 9550). It's unusable without enabling display scaling (labels are too big/icons are too small), and with display scaling it looks a bit fuzzy.
I use redshift which does not support stored procedures.
I want to use Alteryx scheduled workflows as stored procedures, in that I run a set of queries using the Pre SQL statement of an input tool, and do simple counts in the actual Input tool query for error handling and notification (linked to Slack api using download tool)
There is a Pre SQL statement character limit in the GUI, preventing me from running the whole set of queries.
I got around this by putting the set of Sql queries in a formula tool and then feeding that into a macro that uses a control parameter and action tool to update the presql of an input tool.
Please remove the character limit in the input tool configuration GUI. Not sure why there is one?
I've come across multiple requests for help that relate to dates. Having to know that "2016-05-04" is the only way to get May 4th, 2016 into a date field is sometimes a challenge for new users. When they begin to use date functions and now have to learn adding and trimming etcetera the complication factor increases. Then we date time format and have to do all of this in English (my one and only language), makes me think that there is room for improvements.
What I'd really like to see is In-DB connection with Netezza. Having it available for the input tool is OK but a sore consolation to taking advantage of the speed provided by I
Sometimes we may have polygons, such as county boundaries, and need to split the polygons into smaller areas using polylines, such as roads. Please consider adding a polygon split by lines tool. I imagine it could be like the Poly-Split tool, but accept two inputs of a polygon field and a polyline field.
For those with large web and streaming-media server logs, the ability to geocode IP addresses be an excellent feature, similar to Alteryx's ability go geocode street addresses. Several IP geocoding services exist, with different levels of accuracy and cost. Ideally, the user should be able to choose their own service if they have one, in addition to a default service built-in to Alteryx.
A proof of concept is documented in this post.
The IP geocoding tools should include:
I work with data where milliseconds is my saviour when I count distinct the datetime to get number of events. Alteryx ignores the millisecond part (as lots of other BI tool providers - I don't know what is going on with this idea that milliseconds are not needed). Yes I can convert it to string but it's not the best practice to create duplicate fields just so that I have date part for date-related calculation (plotting, time difference) and on the other hand string value for quick and easy counting..
