SummaryWriter is not fully functional

I want to implement this function, but need your assistance. Thanks.

A contribution with the missing functions will be welcomed. :-)

[NiklasGustafsson]

BTW, @ChengYen-Tang, since you've reported issues with 0.99.2 -- 0.99.3 is out on NuGet, now.

[NiklasGustafsson]

@ChengYen-Tang -- I was sent some emails with comments, which you must have deleted.

The TB format is complicated, and needs to be reverse-engineered. I found the TB source code helpful, but not sufficient, and so I had to re-learn to use the binary file viewer in VS...

Lots of hex-decimal-hex conversion involved... :-)

I found another solution 🤣

@NiklasGustafsson,
Can I install NumpyDotNet to TorchSharp?

When I saw these code, my head was painful😭

[NiklasGustafsson]

No, that is not an acceptable dependency to introduce.

Maybe I can achieve the same functionality using torch.
These are the features I found missing.

@NiklasGustafsson,

add_hparams needs your help to add these components

Do you have an image processing library that you recommend, because we need to draw boxes in pictures.

As a dependency for TorchSharp? We've taken a dependency on SkiaSharp for reading and writing images.

If you're looking for a general recommendation, ImageSharp is also good, and runs everywhere, since it's pure .NET. Just read the license and make sure it works for your situation.

@ChengYen-Tang
We had this discussion before and why the SkiaSharp with MIT license is a better choice than the ImageSharp with Six Labors Split License.

[ChengYen-Tang]

@NiklasGustafsson @GeorgeS2019,

I have a problem, SkiaSharp can't combine multiple images into one gif
add_video() store gif as base64 string

mono/SkiaSharp#237

[ChengYen-Tang]

If we want to achieve this function, I feel that ImageSharp is more convenient.
TorchSharp is an open source project and should be available unconditionally?
