QUESTION
I would greatly appreciate any feedback you might offer regarding the issue I am having with my Word Prediction Shiny APP Code for the JHU Capstone Project.
My UI code runs correctly and displays the APP. (see image and code below)
Challenge/Issue: My problem is that after entering text into the "Text input" box of the APP, my server.R code does not return the predicted results.
Prediction Function:
When I run this line of code in the RConsole -- predict(corpus_train,"case of") -- the following results are returned: 1 "the" "a" "beer"
When I use this same line of code in my server.r Code, I do not get prediction results.
Any insight suggestions and help would be greatly appreciated.

I'm trying to link OpenGL to an application for Windows (building on Windows).
I'm using Conan as package manager, CMake for building and MSVC as compiler (and CLion as IDE).

Answered 2021-Jun-10 at 14:30I'm compiling with
GL_GLEXT_PROTOTYPES=1
.
Well, don't do that. That is never going to work in a portable way. On windows, the opengl32.dll
always exports only the functions which are in OpenGL 1.1, and for everything beyond that, you have to rely to the OpenGL extension loading mechanism at runtime.
I have tried:
- [...]
- Adding GLEW
That's a step in the right direction. But this does not make things to magically work. A GL loader like GLEW typically brings its own header as a replacement for GL.h
and glext.h
etc., and the typical GL loader (like GLEW) simply re-define every GL functions as a macro, like this:

One is to use a combined character, as illustrated here with Python's built-in ascii

QUESTION
There's tons of info about Unicode codeunits, codepoints, etc, but I'm still a bit fuzzy about converting combined characters, graphemes, etc using byte-streams (required by libiconv).
Currently I'm only interested in converting between UTF-8/UTF-16/UTF-32 using libconv's iconv()
, which expects the byte-lengths of both source and destination buffers as arguments.
Question: Is there a safe way to calculate fast the maximum possible bytes-length of the target buffer, based on the already known bytes-length of the source buffer?
Let's say for example, converting from u16buf
to u8buf
with a known u16byteslen
(excluding 0x0000-termination if any). In the worst-case scenario, there will be 1 two-byte unit per codepoint in the UTF-16 source buffer, corresponding to a 4 single-byte units per codepoint in the UTF-8 target buffer. Is that enough to safely assume that the UTF-8 target buffer can never be longer than 2 * u16lenbytes
?
I've actually experimented with that and seems to work, but I'm not sure if I'm missing corner cases involving combined characters and grapheme clusters. My doubts come from my ignorance regarding how those things are converted across these 3 different encodings. I mean, is it possible for a grapheme to need say 3 UTF-16 codepoints but like 10 UTF-8 codepoints when converted?
In that case, doubling u16lenbytes
wouldn't suffice, right? And if so, is there any other straight forward way to pre-calc the maximum length of the target buffer?

Yes.
to UTF-8 to UTF-16 to UTF-32 from UTF-8 ×2 ×4 from UTF-16 ×1 ½ ×1 from UTF-32 ×1 ×1You can calculate this yourself by breaking it down by code-point ranges. Pick a source and destination column, and find the largest ratio.
Code Point UTF-8 length UTF-16 length UTF-32 length 0000…007F 1 2 4 0080…07FF 2 2 4 0800…FFFF 3 2 4 10000…10FFFF 4 4 4Combining characters and grapheme clusters do not affect anything. Encodings simply convert a sequence of Unicode scalar values to bytes, and they are very straightforward.
Note that you will need to add two extra bytes when converting to UTF-16, and four extra bytes when converting to UTF-32, since these encodings will add a BOM U+FEFF to the beginning of the text. (If you don’t want that, use one of the BOM-less encodings, like UTF-16BE
or UTF-16LE
.)
I mean, is it possible for a grapheme to need say 3 UTF-16 codepoints but like 10 UTF-8 codepoints when converted?
No. That would imply some other kind of conversion, like a decomposition. The number of scalar values input is equal to the number of scalar values output, with the possible addition of U+FEFF byte order mark at the beginning. (I say "scalar value" instead of "code point", because "scalar value" excludes surrogates. If you are transcoding text which might have errors or might be garbage data, it doesn’t change the size of the result.)
QUESTION
I have run some Python code in Windows 10 and gotten the Traceback error below. Does it mean the string that is supposed to be an int occurs in line 347
of /DeOldify/deoldify/filters.py
or line 1943
of /lib/site-packages/PIL/Image.py
?
For context, below the traceback error, I've also included the steps that lead to this error (I attempted to colorize a black and white film clip based on the DeOldify Colab https://colab.research.google.com/github/jantic/DeOldify/blob/master/VideoColorizerColab.ipynb but only succeeded at colorizing the first frame as a .jpeg) and the full terminal output.
EDIT: Thanks to @Daweo's response, I discovered the problem was with the arguments I entered into the terminal as indicated by "", line 1
. The correct command should have been:
video_path = colorizer.colorize_from_file_name(file_name='my_video.mp4', render_factor=render_factor)

QUESTION
I am trying to develop a project and I'm having trouble installing a Sylius with composer.
Here is my composer.json
ANSWER
Answered 2021-Jun-03 at 16:19You have two problems:
- You have Symfony '5.3' installed, which was released just one day ago.
- You are using PHP 8, which is not supported by Sylius. By using PHP 8, you end up installing versions of dependencies that are not compatible with Sylius.
Since the current version of Sylius supports up to 5.2, and PHP ^7.3, you'll have to either downgrade to Sf 5.2 and PHP >= 7.3 && PHP < 8, or wait a some time so support for Sf 5.3 and PHP >= 8 is baked in.
I would recommend using the standard Sylius installation, but trying to install Sylius with the recommended docs way (composer create-project sylius/sylius-standard acme
) when using PHP 8 also fails. But downgrading to
PHP 7.4 and running the create-project
command does work.
The project seems to have entered the dependency hell stage of development.
