QUESTION
Here's my .vimrc
...ANSWER
Answered 2021-Apr-26 at 09:44Welcome to Vim!
I think most new vim users have been there. I certainly have! I wanted a 'vim as python IDE' and copied a whole bunch of stuff from every blog under the sun into my vimrc almost immediately after installing vim.
After some time spent fighting with all the settings, plugins and remaps I didn't understand, I decided to go through my vimrc, line by line and comment out anything I didn't understand (nearly all of it).
Then I used this more minimal vim for a while and whenever I decided I had a need for a certain feature, I checked the largely commented vimrc for anything that looked related, and/or googled for that particular feature only. Often you find that there is a built in method to do it with the core vim commands, and if not, then there are a lot of solutions for the problem (and often, you find that there is an even more powerful way that didn't occur to you - these are good days).
But the key is to not try and coerce vim into a huge IDE overnight! Let it happen gradually and things will make more sense, and you'll end up with a vimrc that you understand and therefore be in a position to add to it and tweak it.
The last thing I'll say is to recommend the following books:
'Learn VimScript the Hard Way' by Steve Losh
'Practical Vim' by Drew Neil, and his accompanying screencast series.
(Also there is The Primagean who does high quality youtube tutorials)
Having said all that, and acknowledging that an objective answer can't be given for your question, here is a minimal vimrc which has a few plugins and settings that do simple but very useful things (but do read up on them to understand how they work!):
QUESTION
I'm trying to add a symbol in my Altair chart so the user could know by color what each line represents in the chart, but when I plot it I receive an empty chart without the data I'm passing.
Meanwhile I was debugging the code and I suppose the problem is located on the line color = alt.Color...
ANSWER
Answered 2021-Apr-18 at 03:08You cannot use "Symbol" as the chart color because it is not a column in your dataframe. You would need to reshape/melt the df first to create this column, e.g. with new_df.melt(id_vars=['amostra', 'media'], var_name='Symbol']
as per the pandas docs on reshaping.
QUESTION
Tensorflow 2.4.1 doesn't recognize my GPU, even though I followed the official instructions from Tensorflow as well as the ones from NVIDIA for CUDA and NVIDIA for cuDNN to install it in my computer. I also installed it in conda (which I'm not sure if it is needed?).
When I try the official way to check if TF is using GPUs, I get 0:
...ANSWER
Answered 2021-Mar-16 at 18:01After quite a bit of extensive research, it finally works on my computer: the latest versions of the components (i.e. CUDA 11.2
, cuDNN 8.1.0
) are not tested and not ensure a working result in TF 2.4.1. Therefore, this is my final configuration:
nvidia-drivers-460.39
haveCUDA 11.2
drivers. However, you can still installCUDA 11.0
runtime and get it from the official NVIDIA archive for CUDA. Following the installing instructions is still mandatory (i.e. adding the path variables and so on).cuDNN
library needs to be on the version 8.0.4. You can get it also from the official NVIDIA archive for cuDNN
After installing both components on these specific versions, I successfully get:
QUESTION
ANSWER
Answered 2021-Mar-01 at 08:44The exchange you see is Lightstreamer protocol and only some values are determined by the app.
This protocol is based on javascript and it is used by old client libraries; for instance, the LS_e function is provided by the client library.
There are several protocols available to the clients; one of them, TLCP, based on pure text, is public and documented here.

QUESTION
I have DataFrame with multiple columns and few columns contains list values. By considering only columns with list values in it, duplicate rows have to be deleted.
Current Dataframe:
...ANSWER
Answered 2021-Jan-25 at 05:10You can convert each of the columns with lists into str and then drop duplicates.
- Step 1: Convert each column that has lists into a string type using astype(str).
- Step 2: use drop_duplicates with the columns as strings. Since you want all duplicates to be removed, set keep=False.
- Step 3: drop the temp created astype(str) columns as you no longer need them.

QUESTION
I am developing my own dpdk application utilizing multiple rx/tx queues. My application runs perfectly fine with Intel 82599ES NIC. However, I want to run my application on FM10420. I use an FM10420 virtual function (VF) since my PF need to be bound to fm10k driver to control the switching fabric. Upon running my application on FM10420 VF, the RX Queues become empty after few seconds along with following two dmesgs on host computer,
...ANSWER
Answered 2020-Dec-21 at 04:40After doing few tests with example/skeleton
and my own dpdk application I have found that the problem is with using rte_eth_tx_buffer();
to buffer my packets to TX queues. I have replaced it with rte_eth_tx_burst();
which will transmit my packets as single packet bursts. However, I guess this could affect my TX performance but I haven't done any performance tests yet.
I have no idea how fm10k have a problem with rte_eth_tx_buffer();
. ( Maybe because of FM10K does not support HW offload for VF
? )
Update:
I have found my mistake. I have used rte_eth_tx_buffer_init(tx_buffer, 1))
instead of rte_eth_tx_buffer_init(tx_buffer, MAX_PKT_BURST))
which essentially make only 1 TX buffer initialized. I'm not sure how it wasn't a problem on other NICs, but FM10420 certainly did.
QUESTION
Recently I've been trying to learn how to webscrape in order to download all the images from my school directory. However, within the elements they are not storing the images under the img tag and instead have them ALL under this: background-image: url("/common/pages/GalleryPhoto.aspx?photoId=323070&width=180&height=180");
Anyway to bypass this??
Here is current code that will download images off of a targeted website
...ANSWER
Answered 2020-Nov-04 at 02:25You can use the internal API this site is using to get the data including the image URL. It first gets the list of staff groups using the /settings
endpoint then calls the /Search
api with all the groupID
The flow is the following :
get the
portletInstanceId
value from a div tag with attributedata-portlet-instance-id
call the settings api and get the groups ID:

Here is the code that I am currently using to download images from websites.
...ANSWER
Answered 2020-Nov-02 at 11:51I will get you well on your way. You cannot easily do this just with requests
because the site's content is loaded after the main page by JavaScript executing AJAX calls to load more content that updates the DOM
. You really need to use a tool such as [Selenium]
(https://www.selenium.dev/downloads/) that will drive a web browser such as Chrome (or your choice) where you can wait for the elements you are looking for to appear. Even then it is not that straight forward. First, the photos are across multiple pages. The code below only processes the first page. You would then need to drive the browser to click on areas of the page to force the next page of photos to load.
Once the page content has loaded, I use Selenium's ability to find elements by its XPATH to retrieve all the elements that contain the
style="background-image: url('some-value'"
. I then have to retrieve from these elements the style
attribute and from that I have to look for the background-image
url specification, which could be an empty string. Finally, I use a thread pool to retrieve all the URLs concurrently using a request
Session
object, which is more efficient. BeautfulSoup
is not used at all. Finally, I do not use a randrange
call to generate the name of the file since there could be a collision and you wouldn't want to attempt to store two images with the same name (and certainly not concurrently).
QUESTION
My problem may be simple but I have been going round and round trying to understand what the problem is. I have a Blazor page with separate model class (references as LsC for the List
or ls for single when looped in code) that loads the data. But when I click to update that data the page does not refresh. If I add a new entry, that page does load the new entry.
The Blazor page code with the problem is simple:

Answered 2020-Aug-27 at 17:39I guess you are calling databse method on OnInitialized() method
Can you try the same using StateHasChanged() you can find the documentation here
Otherwise only solution is to change the value of the item which you are binding in your UI
