I have URL http://localhost:3000/share/user=sampleuser which should display objects that have a author value matching that of the one in the URL. I'm getting an error when trying to call a function that takes the value from the URL then performing a find function in the database to find all entries matching the user.

QUESTION
I have a very large pandas data frame and want to sample rows from it for modeling, and I encountered out of memory errors like this:
MemoryError: Unable to allocate 6.59 GiB for an array with shape (40, 22117797) and data type float64
This error is weired since I don't need allocate such large amount of memory since my sampled dataframe is only 1% of the original data. Below is my code.
Specifically, the original data has 20 million of rows and most of them are np.float64 data. After loading the data from parquet file using pyarrow, the jupyter kernel takes about 3 GB memory. After the variable assignment using "d0['r_%s'%(t)] = d0.col0", the kernel takes 6 GB. However, once I run the sampling command "d0s = d0.iloc[id1,:]", the memory goes up to 13 GB and the program stops due to out-of-memory error above.
Below code is a minimal working example to reproduce the error on a 16GB memory machine using pandas 1.2.3.
...ANSWER
Answered 2021-Apr-04 at 20:46I found that the error is due to the consolidation operation pandas performed. Specifically, after the variable assignment using "d0['r_%s'%(t)] = d0[0]", d0 is stored in 13 blocks, i.e.: 13 contiguous memory space, and this could be checked using command

QUESTION
i click a link and copy a div and create a li for this copied div into the ul list. When i remove a created div, the counter resets the elements, but how can i update or remove the associated li that i created? I tested many things. Firstly i checked the text of the div that clicked to remove and if text is same as a li text then remove the li. That is working, but i removed it, sometimes there was a bit weired behavier, perhaps you can help me here too. But how can i update the li. For example added three new entries: Test2, Test3, Test4. Now i removed Test3, it recounts the Div Texts to Test2,Test3, but in the li list it is: Test2,Test4. So, would be great if you help me: to delete the associated li when element removed and recount the associated li -> text and id when resetindexes. I searched many times, but have no clue :-(
...ANSWER
Answered 2021-Mar-11 at 14:00You can assign custom attribute to your li
tag which is added dynamically and add that as well to your span tags then whenever your remove
is click get the data-attribute
of span and use this to remove li
then reassign values to all elements .

I am trying to publish a website to my IIS server thats running on a Windows Server 2019. When I publish the site all the files get transfered but in a very weired looking format, theres an .exe file and a lot of .dll files. I am used to .html files. But when I try to get into the website I get all kinds of error codes and by almost a day of research and experiments I've come up with that I dont have a default page. As I have .cshtml pages in my project I dont have any page at all in my published version. There is so much I could upload here so I dont know what to actually upload so just ask in the comments and ill upload everything you need. Thanks beforehand!!!

may both hit the network to look up imported packages that aren't provided by any required module.
If a module is replace locally, the go command will look there first, but I think it may still go out to the network for other prefixes of the module path.Instead, you can add a requirement on a non-existent version while replacing that version:

this.httpService.get('/user/appUser').pipe(
concatMap(users => users),
concatMap(user =>
forkJoin({
billingAddr: this.httpService
.get('/user/appUserAddr', new HttpParams()
.set('where', JSON.stringify([{ pk_addr_name: user['fk_billing_addr_name'] }]))

}).pipe(map(addr => {
user['billingAddr'] = addr.billingAddr;
user['shippingAddr'] = addr.shippingAddr;
return user;
}))
),
tap(res => console.log(res)),
toArray()
);
...ANSWER
Answered 2021-Feb-19 at 11:28This is certainly an interesting question. Here whats happening
- Get initial array.
- First
concatMap
emits each element of the array sequentially. Akin tofrom(array)
. - Map to observable from
forkJoin
using secondconcatMap
. - Adjust each element by fetching and assigning two new properties to it using
forkJoin
. - Combine all the elements/emissions at the end again as an array using
toArray()
operator and emit.
I don't see anything wrong with it except you're waiting the current user to fetch it's data before starting the next.
However if you wish to completely parallelize the fetches, you could use two forkJoin
s. Inner forkJoin
is similar to existing usage and outer forkJoin
to replace the concatMap
and toArray
. Here the switchMap
could be replaced with any other mapping operator. Since Angular HTTP request completes after the first emission, the type of mapping operator used doesn't have any impact.
Note: This is untested code. Please report back any unintended consequences.

Answered 2021-Feb-19 at 04:23The problem is that your read_json(....).text
line returns a series, not a dataframe.
Adding a .to_frame()
