kandi X-RAY | klaus Summary
this is a show-case of how to run a state-of-the-art image classifier from ios devices. warning ahead, this is a show-case, and it is open-source. however, the ccv’s xcode project presented here will not be maintained. using full ccv implementation: deep learning based image classifier normally has large memory footprint. ccv’s default image classifier uses around 220mib memory, which is reasonable on desktop, but a bit too much on mobile devices. a deep learning based image classifier also comes with large data files (so-called pre-trained model), ccv’s pre-trained model is about 110mib, [caffe] is about 200mib, and [overfeat] is about 1gib. delivering a mobile utility app with 100mib data file is quite unreasonable. in [klaus] accuracy is scarified for smaller memory footprint as well as smaller data files. specifically, on imagenet 2012, ccv’s default image classifier has top-5 missing rate at 16.17% (meaning that given an image, for total 5 guesses, ccv’s default image classifier has 83.83% chances to get it right). the mobile-friendly image classifier has top-5 missing rate at 18.22%. this is achieved with a 19.3mib pre-trained model. the first difference of this new mobile-friendly image classifier is its full connect layer size. ccv’s default image classifier follows matt’s model, and thus, the full connect layer has 4096

...ANSWER
Answered 2021-Jun-09 at 09:43As a general tip, you can use map
to easily access values from nested lists. The following uses this approach while returning a count of 0 if a female or male value is absent from a list element. This also works if one or more of the values in male_female_row
is formatted as a character, not a number:

QUESTION
I need your help! I need a regex, that matches the following phone number formats (Germany, Austria, Switzerland). I have no idea, how to create this regex.
What I need are phone number formats as follows:
+49 (089) 1234567890
+43 (01) 1234567890
+41 (051) 1234567890
Only the mentioned country codes (+49, +43, +41) can be filled in this way (including plus sign). No 0049 or (0049) or (+49) etc.
Subsequent a space character should be between the country code and the area code. No other characters like -, /, + etc. or letters are allowed. Only space character.
The following area code must have brackets.
Subsequent a space character should also be between the area code and the phone number. No other characters like -, /, + etc. or letters are allowed. Only space character.
The phone number should be filled in its entirety (only numbers are possible and there are no spaces between the numbers).
I hope, someone can support me and my request, because I really don't know how to create this expression. I tried it and that is the result:
[0-9]*\/*(\+49)*(\+43)*(\+41)*[ ]*(\([0-9]{3,6}\))*([ ]*[0-9]|\/|\(|\)|\-|)*
I guess, this is totally wrong.

QUESTION
My project structure looks like this:
- /definitions (for all dagster python definitions)
__init__.py
- repositories.py
- /exchangerates
- pipelines.py
- ...
- ...
- workspace.yaml
I've tried running the grpc server using various methods, especially the following (started in project root):
dagster api grpc -h 0.0.0.0 -p 4000 -f definitions/repositories.py
dagster api grpc -h 0.0.0.0 -p 4000 -m definitions
dagster api grpc -h 0.0.0.0 -p 4000 -m definitions.repositories
The first command yields the following error:
dagster.core.errors.DagsterImportError: Encountered ImportError:
attempted relative import with no known parent package
while importing module repositories from file C:\Users\Klaus\PycharmProjects\dagsterexchangerates\definitions\repositories.py. Consider using the module-based options-m
for CLI-based targets or thepython_package
workspace.yaml target.
The second and third command yield the following error:
(stacktrace comes before this)
ModuleNotFoundError: No module named 'definitions'
How can this be solved?
EDIT: I've uploaded the current version of the example I'm working on to GitHub: https://github.com/kstadler/dagster-exchangerates
EDIT2: Reflected changes in directory structure
...ANSWER
Answered 2021-Jan-23 at 18:48sorry about the trouble - there are a couple of options here to get your server running.
To get it working with the '-f' option, the relative imports need to be replaced with absolute imports. That would look like this:
QUESTION
I have a list of words (find_list) that I want to find in a text and a list of expressions containing those words that I want to bypass (scape_list) when it is in the text.
I can find all the words in the text using this code:
...ANSWER
Answered 2021-Jan-14 at 19:55You can capture the word before and after the find_list
word using the regex and check whether both the combinations are not present in the scape_list
. I have added comments where I have changed the code. (And better change the scape_list to a set
if it can become large in future)
QUESTION
So I have the following dataframe, but with a valuable amount of rows(100, 1000, etc.):
# Person1 Person2 Age 1 Alex Maria 20 2 Paul Peter 20 3 Klaus Hans 30 4 Victor Otto 30 5 Gerry Justin 30Problem:
Now I want to print separate dataframes, which contain all people, that visit the same age, so the output should look like this:
DF1:
# Person1 Person2 Age 1 ALex Maria 20 2 Paul Peter 20DF2:
# Person1 Person2 Age 3 Klaus Hans 30 4 Victor Otto 30 5 Gerry Justin 30I've tried this with the following functions:
Try1:
...ANSWER
Answered 2021-Jan-10 at 21:06In your first try, you are looping through the length of dataframe and then repeating the below line every time replacing x with 0,1,2,3 and 4, respectively. On a side note, x = x + 1
is not required. range
already takes care of that.
QUESTION
There exists a DataFrame like this:
id name age 0x0 Hans 32 0x0 Peter 21 0x1 Jan 42 0x1 Simon 25 0x1 Klaus 51 0x1 Franz 72I'm aiming to create a DataFrame that covers any possible combination within the same ID.
The only possibility for ID 0x0 is Hans and Peter. Since ID 0x1 exists four times, there are six possible solutions, as shown in the table below.
Since this is an example, one ID could also exist three, five, seven, ... times which results in more or less possibilities.
id name0 age0 name1 age1 0x0 Hans 32 Peter 21 0x1 Jan 42 Simon 25 0x1 Jan 42 Klaus 51 0x1 Jan 42 Franz 72 0x1 Simon 25 Klaus 51 0x1 Simon 25 Franz 72 0x1 Klaus 51 Franz 72Using combinations, I can already cover the possibility aspect, but I am losing the ages of each name on the way.

to get the age
