You are confusing a few things here (I think)

Freezing layers

You freeze the layer if you don't want them to be trained (and don't want them to be part of the graph also).

Usually we freeze part of the network creating features, in your case it would be everything up to self.head.

After that, we usually only train bottleneck (self.head in this case) to fine-tune it for the task at hand.

In case of your model it would be:

react slider prevent image reload on change

I'm making an image slider with React and running into an issue where the images are being re-requested from the remote URL

Here's a JS Fiddle that illustrates the issue: https://jsfiddle.net/iioinc/sz8pf245/

When I first open the image slider and go to the next slide, the first and second images are loaded. Then when I go to the previous slide, the first image loads again. This continues on each slide change - the images get requested again from the same remote URLs:

The best solution so far is it use DPR values in srcset and get rid of sizes. The only problem with that solution is that it is going to use 990w image on DPR:2 mobile screens, like iphone 6/7/8

QUESTION

Kernel errors when using FMX BeginDragDrop to another application

Asked 2021-May-17 at 19:39

Update:

Indeed, the issue was fixed since 10.2. I compared the FMX.Platform.Win from 10.4, the fix is in the function TWinDropTarget.GetDataObject: TDragObject;

I've implemented the answer for Drag and drop with TTreeView in Firemonkey to drag&drop TTreeViewItems in a Delphi 10.2 FMX Windows application.

Everything is working perfectly within the same app, however when the user suddenly drops an item to another copy of the same app, it hangs or even shuts down with c0000374 external error.

When trying to debug in the IDE, the source app stops with this system call stack:

I don't actually need the ability to drag between applications (although, it would be perfect). I'm just asking, how to avoid such errors?

According to the comment below, I've added a minimal example. Create a Win32 FMX app and add a TLabel to it:

Install DPR

Installation from the source. Python's virtual or Conda environments are recommended. DPR is tested on Python 3.6+ and PyTorch 1.2.0+. DPR relies on third-party libraries for encoder code implementations. It currently supports Huggingface (version <=3.1.0) BERT, Pytext BERT and Fairseq RoBERTa encoder models. Due to generality of the tokenization process, DPR uses Huggingface tokenizers as of now. So Huggingface is the only required dependency, Pytext & Fairseq are optional. Install them separately if you want to use those encoders.
