To install the `sympy` module on Windows, type CMD in the search bar and open Command Prompt and type
pip install mpmath, first and then pip install sympy.
put ice dll and secp256k1.py in the same folder where you have the script.

Thanks, I did what you said and learned a few things about python commands, after a few errors now it says module secp256k1 has no attribute 'pub2upub' even though I correctly pasted the upub in it's place. I went to secp256k1.py and there was no mention of pub2upub. Lol this thing burned more energy than a week of dealing with EC math.

Now, if it were possible to calculate an even target pub or an odd one, then 130 puzzle could be solved in a few hours.

You can't figure out if a key is odd or even, that would make it easy to find every other digits to see if they are also odd or even.

But there is a way to make sure that the correct results are in your files and your tool had all the incorrect and correct keys.

Here is how, you know some keys can be divided by 2 a few times in a row, so when you divide a key you need to divide it by 2 at least 4 times, subtract 1 from all and do the same with all the keys. This should occupy less than 1 GB of storage/ RAM, and it should solve the low bit range keys in minutes, but I don't know why nobody is trying it.🤔

Code:

target_public_key = "03633cbe3ec02b9401c5effa144c5b4d22f87940259634858fc7e59b1c09937852"
pub = ice.pub2upub(target_public_key)

replace the line with this, the pub should be compressed, don't forget to copy secp256k1.py and ice_secp256k1.dll in the same folder where your script is located.
