What is occuring is that you need webdriver waits and wait for visibility for all elements.
I am having an issue related to validating cryptocurrency wallet addresses, specifically USDT.
USDT can be validated either as a BTC or ETH address, depending on the network type.
Basically it goes like that:
- If cryptocurrency is USDT and chain type is ERC20, validate the address against ETH address format.
- If cryptocurrency is USDT and wallet type is OMNI, validate the address against BTC address format.
I haven't managed to find a specific validation for USDT:TRC20 addresses and I am not sure how to validate them....

I am developing a regression model to predict cryptocurrency prices, and I have created a simple loss function. The idea is simple the Y target is the price change from a certain lookup window, so either the values are positive or negative. The idea is to first apply an mae loss function and then penalize where y_pred is positive and y_true is negative and vice versa. And reduce the loss where y_pred is positive and y_true is also positive and vice versa. Yet when I train with my loss function the precision does not get higher then 0.50 where it gets to around 0.535 with the regular mae loss function. Any idea what could cause this?
The loss function:...

Any idea what could cause this?
Assuming you set the seed for reproducibility, otherwise it could simply be initialization, when you change the loss function you change the domain over which the gradient is going to iterate to optimize your network.
And since you don't have any guarantee that your model is going to reach the global minima but, most likely, will stop at a local minima it coud just mean that, given the same initialization (set seed) the optimization process stopped at a different local minima.
I am running a Cryptocurrency-trading python program on my laptop It monitors the market every second and when the condition is satisfied, it tries transactions.
When I run it on windows CMD, it causes many problems below.
1. Sometimes, it halts till I click the cmd window and press 'enter' key
2. Sometimes, it causes many unknown errors.
However, when I run that on VScode, it does not cause any problem.
I wonder what makes the difference between those two environments....

I have had some issues with VSCode not finding libraries and similar, and the reason for that is that VSCode runs its own python. In IDLE (and CMD) you run the raw python in AppData, but VSCode runs an executable they have downloaded via extensions through the program files folder. My hypothesis is that Python as in the AppData folder is corrupted or wrong in some way, but the Program Files folder is correct. It may even be on a different python version.
Try reinstalling python from the official python website, and run it again. Also double-check that the VSCode Python extension version is the same as the one saved in "C:\Users\YOURUSERNAME\AppData\Local\Programs\Python\Python39".
Hope it worked!

I have two datasets that I am trying to plot over each other.
The first dataset is the daily price of Dogecoin. I am using yfinance and mplfinance to chart this.
The second dataset is a CSV file of Dogecoin wallet transactions, which has a column named "Balance", that shows the Balance of the Dogecoin Wallet at the time of the transaction. The balance fluctuates as cryptocurrency comes in/out. Below is the CSV for reference.
I am trying have the Balance as a line chart, to show the fluctuations in balance.
Below is my code. What I am trying to accomplish with this code is to chart the Dogecoin Price, then chart the Balance from the CSV as a line chart, and have the charts overlayed with each other. When displayed on the chart, I am trying to have the dates from both datasets be the same, so the data is properly displayed.
The first problem is I have been unable to figure out how to plot these two charts over each other. The first chart comes from mplfinance and the second chart comes from matplotlib. If these two modules cannot plot over each other, then I can use a csv of the Daily dogecoin price instead of mplfinance and yfinance.
The second problem I have ran into is my Balance plot does not fluctuate when the balance decreases, it only increases....

Before you can line up the timestamps from the two data sets, there are a number of issues with the csv file that have to be cleaned up first.
This is what the csv file looks like as you are reading it:
I'm a total beginner with Python/Django and trying to understand why this isn't working. I have a
function that contains a
for loop, doing some logic and then updating a model. but when I have more than 1 item in the loop I get a
UNIQUE constraint failed: app_token.token_name error.
So I think I'm misunderstanding how the loop is working?
ANSWERAnswered 2022-Jan-22 at 10:31
I believe that by calling Token.objects.update() you actually end up trying to update all Token objects. Since token_name has to be unique, and you are giving it the same name as another Token object it throws that error. Since you are already in a for loop, you can simply update the token that is currently being processed.
My suggestion would be to use this code instead:
Creating a scatter plot with vega points are only plotted up to the 11/12th of every month? I'm confused as I feel like everything should be working fine, however this clearly doesnt seem to be the case. Is this due to the data? or the choice of graph maybe? Feel as though there should be a solution but going through the documentation i can't find one...

Your source data appears to store dates using
MM/DD/YYYY. Because of this, when the day is larger than 12, the result is an invalid date.
You can fix this by declaring the correct date format in your specification:
