RPN | An exploration in implementing an Reverse Polish Notation

• Using FileMetadataDirectory instead of ExifSubIfdDirectory
• Using random jpg from output-onlinejpgtools.jpg

That's a big query, possibly too big for StackOverflow volunteers to wrap our heads around. I do notice one thing, though: you have multiple occurrences of

I believe that model.fit_generator is deprecated, in TensorFlow 2.2 and higher you can just use model.fit because this now supports generators.

You have the same behavior with this simple exemple

Splitting your string works as expected, the problem is that you incorrectly manage the values on the stack. Instead of trying to re-read (and re-parse!) the values from the string vector (which might, in worst case, lead to evaluate an operator as a double, resulting in an exception) you should fetch your already parsed values from stack, apply the operator and push the result back, as follows:

When the code finds a number, it should increment i by two, unless doing that the code does not work.

Therefore, the else condition could be written as follows(The rest of the else statement will remain intact):

It looks like cloud-vpn only supports IPsec and is not compatible with the OpenVPN protocol used by Scaleway's RPN-VPN.

To do a site-to-site vpn connection you'll need one of those:

• cloud-vpn compatible ipsec gateway on a Scaleway server connected to RPN v1
• a custom gateway connected on gcp with an openvpn client to RPN-VPN

With ANTLR, it's usually very helpful to label components of your rules, as well as the high level alternatives.

If part of a parser rule can only be one thing with a single type, usually the default accessors are just fine. But if you have several alternatives that are essentially alternatives for the "same thing", or perhaps you have the same sub-rule reference in a parser rule more than one time and want to differentiate them, it's pretty handy to give them names. (Once you start doing this and see the impact to the Context classes, it'll become pretty obvious where they provide value.)

Also, when rules have multiple top-level alternatives, it's very handy to give each of them a label. This will cause ANTLR to generate a separate Context class for each alternative, instead of dumping everything from every alternative into a single class.

(making some stuff up just to get a valid compile)

A couple of issues.

You are passing the param off into the in_view() function, however the functions return statement is referencing offset which is undefined.

Then you are placing an inline style to the .js-scroll elements for an opacity of 0 using JS in the forEach loop. That inline style will override the computed style coming fromt he class when it is added, therefor your opacity will never actually be set to 1 regardless of the addition of the class that defines the opacity property to 1.

TEST: First fix your parameter naming issue and rename the return in the in_view function to off, then you can run your scroll event and then look at the inspector and it will be right there in the inline style attribute, style="opacity:0; along with the class,scrolled-proj that is supposed to change the opacity to 1.

To fix this create a helper css rule that initializes the opacity property using a class and not an inline style created with javascript.

So change the in_view function to reference the correct param, off, then add a CSS class that sets opacity to 0. => a class to the initial loop that iterates over the .js-scroll elements like this...
