QUESTION
I want to train the CSRNet model on UCF_CC_50 dataset but occurring this problem
...
ANSWER
Answered 2021-Jun-03 at 13:08You are reading a matfile '...\ground_truth\GT_IMG_1.mat'
corresponding to the image '...\IMG_1.jpg'
. While you process this data point, you try to access variable 'image_info'
stored in the matfile you read.
As the error message you got states:
KeyError: 'image_info'
The matfile does not contain this variable, 'image_info'
.
to debug, read the matfile and see what are the names of the variables stored there. Notice that naming them is case sensitive.
QUESTION
I am trying to implement a simple iterative guessing scheme within the equation
section in a model, however, I am getting the following error: No viable alternative near token: while
in OpenModelica. Is there a simple explanation to why this while-loop does not work?
ANSWER
Answered 2021-Jun-01 at 21:17Modelica has equations and algorithms. Algorithms work similarly as in most languages and allow while-loops.
Equations are always valid and unordered so if you write v_guess = v_guess*0.95;
it means that v_guess
should always have this value - which only has the solution v_guess=0
- which is likely not what you want.
You can have for-loops in equations, but that is for handling an array where each element in the array have a separate equation - written compactly.
So, if you want to write a while-loop either write it directly in an algorithm section or hide it in a function.
QUESTION
Apologies in advance if this is somewhere else but I've been looking and I'm not good with regex. I'm using regex to compile sentences from a word document containing paragraphs. I need to get specifically the text between 2 indents, or if someone can help me figure out the current regex I have (which is shown later), then that will also work. For example, from the following text;
Here is the image as plain text, though I can't get the formatting the same:
A method, comprising:
storing a first data related to an operation style of a transport in a first area;
storing a second data related to an operation style of the transport in a second area; wherein the first and second data is based on a combined energy consumption efficiency as the transport maneuvers through the first and second area; and
modifying functionality of the transport based on the combined energy consumption efficiency.
The method of claim 1, comprising modifying functionality of the transport to operate at a greatest combined efficiency consumption efficiency while in compliance with one or more of social necessities and vehicular laws.
And here is the text that is actually read in from my function:
- A method, comprising: storing a first data related to an operation style of a transport in a first area; storing a second data related to an operation style of the transport in a second area; wherein the first and second data is based on a combined energy consumption efficiency as the transport maneuvers through the first and second area; and modifying functionality of the transport based on the combined energy consumption efficiency.2. The method of claim 1, comprising modifying functionality of the transport to operate at a greatest combined efficiency consumption efficiency while in compliance with one or more of social necessities and vehicular laws.
All of this is output into one line when I print the read in text from the .docx file
I need to extract the following lines:
storing a first data related to an operation style of a transport in a first area;
storing a second data related to an operation style of the transport in a second area; wherein the first and second data is based on a combined energy consumption efficiency as the transport maneuvers through the first and second area; and
modifying functionality of the transport based on the combined energy consumption efficiency.
My current regex pattern is as follows:

QUESTION
I would like to use the redirection operator to bring the stream from ffmpeg to cv2 so that I can recognize or mark the faces on the stream and redirect this stream again so that it runs under another stream.
One withoutfacedetect and One withfacedetect.
...ANSWER
Answered 2021-Apr-29 at 16:01I'm still not 100% certain what you are really trying to do, and have more thoughts than I can express in a comment. I have not tried all of what I think you are trying to do, and I may be over-thinking it, but if I put down my thought-train, maybe others will add in some helpful thoughts/corrections...
Ok, the video stream comes from the camera into the Raspberry Pi initially as RGB or YUV. It seems silly to use ffmpeg
to encode that to h264, to pass it to OpenCV on its stdin
when AFAIK, OpenCV cannot easily decode it back into BGR or anything it naturally likes to do face detection with.
So, I think I would alter the parameters to raspivid
so that it generates RGB data-frames, and remove all the h264 bitrate stuff i.e.

ANSWER
Answered 2021-Apr-07 at 10:05Two headers that rely to each other are not a show stopper if well-formed. What I observe is that your include guards don't enclose the full header but only part of it, this I think is wrong. The right way to use include guards is shown in this
example header some_component.h

QUESTION
I have the following function using selenium
that works - but I am unable to pass it on. I get the error: InvalidSchema: No connection adapters were found for 'data:image/jpeg;base64,/9j
(full image link below - it works when I stick in a browser tab) when it gets to the response.get()
portion of the code.
Is there a way to bypass opening and saving the image? I just want to be able to upload the full picture of Barry O to Twitter without saving to my local machine. Or do I have to download, save, and re-upload for my "push to Twitter" function? Am I missing a decoding here? Or mis-using the request.get()
? If I don't have to use requests
, that's fine by me!
ANSWER
Answered 2021-Mar-31 at 01:59The response is not a URL its a base64 encode for MIME data:image/jpeg, so you cannot use it for request.get().
