Good day. I am trying to grab a few data from a url however, only a few lines of my script works since it encountered errors. Any idea will do. Thank you

I have source (src) image(s) I wish to align to a destination (dst) image using an Affine Transformation whilst retaining the full extent of both images during alignment (even the non-overlapping areas).

I am already able to calculate the Affine Transformation rotation and offset matrix, which I feed to scipy.ndimage.interpolate.affine_transform to recover the dst-aligned src image.

The problem is that, when the images are not fuly overlapping, the resultant image is cropped to only the common footprint of the two images. What I need is the full extent of both images, placed on the same pixel coordinate system. This question is almost a duplicate of this one - and the excellent answer and repository there provides this functionality for OpenCV transformations. I unfortunately need this for scipy's implementation.

Much too late, after repeatedly hitting a brick wall trying to translate the above question's answer to scipy, I came across this issue and subsequently followed to this question. The latter question did give some insight into the wonderful world of scipy's affine transformation, but I have as yet been unable to crack my particular needs.

The transformations from src to dst can have translations and rotation. I can get translations only working (an example is shown below) and I can get rotations only working (largely hacking around the below and taking inspiration from the use of the reshape argument in scipy.ndimage.interpolation.rotate). However, I am getting thoroughly lost combining the two. I have tried to calculate what should be the correct offset (see this question's answers again), but I can't get it working in all scenarios.

Translation-only working example of padded affine transformation, which follows largely this repo, explained in this answer:

I'm trying to buy tokens using the swapExactTokensForTokens() Pancakeswap Router function), web3 imported in Python.

Problem 1: I keep getting an abi KeyError: 'name'. Here's my code and error below. I'm not sure how to handle this error.

problem 2: Is it possible to call the abi of a token without hardcoding it like I did below?

Many thanks in advance!

At the following site, after entering a search phrase such as "baby" (try it!), the Puppeteer call page.mouse.down() doesn't have the same effect as clicking and holding the physical mouse: https://www.dextools.io/app/bsc

After entering a search phrase, a fake dropdown select menu appears, which is really an UL, and I am trying to click the first search result. So I use code like this

When trying to run truffle migrate --network bsc, truffle usually (not always) manages to deploy the migrations contract, then fails with an error: header not found.

I want to make a python script (for BSC) which keeps track of the balance of that particular token in the wallet. I need the python script to be very fast. Currently with the below code, it takes about 6 seconds for the script to detect the token entering the wallet. Is there a faster, more efficient way to do it? (I added the sleep func to act as some kind of buffer. Don't know if its a good idea though?) Edit: removed the sleep function but still takes 6s.

I'm recently trying to monitor transactions of a contract address on BSC chain for my dex limit order and I finally found a stable solution to monitor the log event -- 'using web sockect connection'.

I am making a decentralized exchange in which I am trying to implement a search functionality where users put either token address, name, or symbol. But the challenge I am facing is that when users search for tokens like BUSD the token present in the user wallet will come on top. for example:-

suppose I have these tokens in my wallet and I am getting this response from web3

Hello I am currently developing a cryptocurrency on the BSC (it is for fun.) I am using BSC Studio and truffle. I was wondering how I can set and icon for my coin I am assuming it is somewhere in Coin.json but I cant seem to find any option that mentions icons does anyone know where I can do this?
