QUESTION
I am working with a Dataframe containing date in string format. Dates look like this: 19620201 so with year first, then month, then day.
I want to convert those dates into Datetime. I tried to use this:
pd.to_datetime(df.Date)
But it doesn't work because some date have the day to "00" sometimes it's the month and sometimes it's even the year.
I don't wanna drop those dates because I still wnat the years or month.
So i tried to write a function like this one:

and generate ouput column by numpy.where

I wrote a Dash program using python and it works on Jupyter notebook. But It doesn't work on server. I send my geometric data on server by: scp data.json username@10.0.0.0:/directory

QUESTION
I have around 70 categories (it can be 20 or 30 also) and I want to be able to parallelize the process using ray but I get an error:
...ANSWER
Answered 2021-Feb-18 at 01:31This error is happening because of sending large objects to redis. merged_df
is a large dataframe and since you are calling get_meal_category
10 times, Ray will attempt to serialize merged_df
10 times. Instead if you put merged_df
into the Ray object store just once, and then pass along a reference to the object, this should work.
EDIT: Since the classifier is also large, do something similar for that as well.
Can you try something like this:
QUESTION
I am trying to translate all the columns called tweet_text
in my dataset. I have about 100,000 rows of data and about 50% of that needs to be translated to English.
The following code works but I am basically running the function to translate the tweets for every single row which takes nearly 2 hours.
Note: x != " "
checks if the tweets aren't empty strings as some of the tweets have just " "
as I removed some of the emojis from them and that was all that was left.
ANSWER
Answered 2021-Feb-04 at 07:55- The code works fine with the sample provided, so additional rows have been added to the sample dataframe, which result in
exceptions
. - Write a function, with
try - except
to catch the invalid rows. - Note that the following code does not use
import swifter
, because it's a module used to speed up.apply
, and wasn't needed for testing.
QUESTION
I am translating large amounts of text using googletrans. But I keep getting this error Unexpected status code "429" from ('translate.google.com',)
as I am making a lot of requests. So what I am trying to do is call time.sleep(1)
after every translation is done to try and see if this will solve it.
Now I know I could do this with a for-loop where I would just loop over the text in the column tweet_text
, translate the word and then sleep for a second.
But I am trying to figure out how I would incorporate the time.sleep(1)
within the lambda function that translates the words in the code below.
ANSWER
Answered 2021-Feb-02 at 05:22So even with time.sleep()
and removing the use of swifter
the issue still persisted. I ended up trying 3 different libraries but they either had the same problem where I was making too many request or they were not able to process the emojis in the data I had.
I landed on this library deep-translator which was able to use the same code with swifter and translate about 5000 rows of tweets in roughly 15 minutes.
QUESTION
I'm trying to calculate (x-x.mean()) / (x.std +0.01) on several columns of a dataframe based on groups. My original dataframe is very large. Although I've splitted the original file into several chunks and I'm using multiprocessing to run the script on each chunk of the file, but still every chunk of the dataframe is very large and this process never finishes.
I used the following code:

QUESTION
I have some pandas code I'm trying to run over a big data-set, and despite using apply it looks like it's essentially iterating and running slowly... advice would be welcome!
I'm trying to group up my data. Each row has a non-unique event ID, and each event ID can contain multiple events. If any one of those events is a specific type, I want every row with that ID to have a specific flag - eg, this type of event happened in this ID. Then I want a to export my data-frame with just the IDs, with that flag showing if the event occured in that ID.
This is the code I'm using:

instead apply

I am pretty new to SwiftUI and with DispatchGroups and DispatchQueues. I would like to create a Button which processes some server requests and then use the returned data with a CoreML model to predict some score. Once, the score is predicted, then the app can navigate to the next screen
Here is the sequence of actions which need to be done before moving to the next screen

You are not waiting for swifter.searchTweet to complete before doing the update.
The first step is to add a completion handler to fetchTweets
. The completion handler is a way of reporting when fetchTweets
has finished the networking.
QUESTION
I have a dataframe that has 15,000 host IP addresses (IP v4 and IP v6) I am trying to check which of these hosts are up(running) by pinging the hosts.
I have the following code that I have written
...ANSWER
Answered 2020-May-16 at 02:00You can do it with a thread pool.
Updated for parameter to timeout ping after 1 second, chunksize 1, more threads and skipping intermediate shell - worked for a small number of IP addresses on my local machine duplicated to 14000 total. Wait time and chunksize may be the most important. By default, ping times out after 10 seconds and threadpool runs 14000/threadcount pings before returning to the main thread. Considering a timeout was hit when testing this code, the updates should be a good improvement.
