ADAS | Advanced Driver Assistance System

You are sending the wrong data to the method,

I have corrected it, you can refer to the below code. myData string is already a JSON string so there is no need to serialize it again.

With most file copying mechanisms I've used in .NET, you have to specify the fully qualified target name of the actual target file - not just a directory to put it in. The documentation on this method calls for a "destination file name".

Try this:

No, no accessibility checker or combinations of accessibility checkers is effective at finding all accessibility issues.

You need someone who knows WCAG, possibly ATAG depending on the application and ADA compliance to test for you.

Accessibility checkers are tools to assists you, unfortunately we are a long way from an automated solution that catches everything.

You need experience and a deep understanding of the WCAG guidance, even if your goal is purely compliance (as I would encourage you to change mindset from "compliance" to "best user experience").

The reason we can't rely on tools yet is because it is difficult to automate some (most) things, for example logical focus order is not something that has been successfully automated yet. (Top tip - accessibility insights has a good tool for testing logical tab order, it still requires some manual work but better than just hitting tab alone.)

Or forms - yes tools can tell you if you are missing a label but they can't tell you if error messages are meaningful, if instructions are clear, if the form label is located close enough to the input to not cause confusion etc.

To give you an idea of how far away we are with automated tools, the UK Government's website accessibility team tested automated tools on the "worlds least accessible webpage".

Out of the 10 tools tested they found that 29% of barriers were completely missed by every tool. (So even if you ran all 10 tools you wouldn't pick up 29% of errors - including manual prompts to check things!)

The most effective at finding errors automatically was Tenon....it found 39% of the accessibility errors.

There is a break-down of how these accessibility testing tools performed here.

In short, they are tools that will help you find about half of the accessibility issues on your app / page.

For everything else you need someone who knows how to test your site and find accessibility errors.

You can try this function:

I was able to figure it out doing the following:

You need to provide the offset for the limit to start at.

One of the problem to use fillna with df.mean() is that if the column contains only nan (or inf before as you replace by nan), then the column is still full of nan after the fillna. One way is to remove the columns that have only nan, because anyway these columns won't be useful for the ML model. To do so, you can use dropna and chain all the methods.

You can sort on the DATE column. But then you need to remember to do sort=False in your groupby, else it will sort there using the string ordering. In addition, your repetitive code for each year can be replaced with a single groupby, adding year to the grouping keys. Then you'd then write separately into different files and index=False is how you get rid of the Index.

It is unbelievable! The problem was just the file extension of the compiled file. As soon as I changed .dll to .pyd, the Python example (example.py) is running without any issue!

So the new command line is:
