This project I'm working on is the same project I was working on when I asked this StackOverflow question: I'm getting a name error when running Selenium-based code. Again, both the questions are related to Selenium. However, this time I am not getting any errors but the website I want to be opened isn't opening. And I'm sure my chrome_directory is right. Idk why Google.com isn't opening. This is my code:

I am trying to use Python on an Amazon EC2 instance, in the same VPC as an Amazon Neptune instance, to add a vertex (node) to Neptune. Using the example code for Amazon Neptune, I constructed the following code sample to add a vertex (node) and then print out all vertices in the graph.

QUESTION
- i'm doing some web development with python's anvil-app-server https://pypi.org/project/anvil-app-server/
- i would like to use the debugger because it is a powerful/useful tool on the server side python code
- i generated a hello-world application named ServerSidePdb
- i put
pdb
andipdb
into the server side callback for the helloworld generated application and got a console output that looks like an error:
ANSWER
Answered 2021-Apr-26 at 17:06- the server side code executes under a java server and the java server captures the stdin/stdout which prevents you from directly running pdb or ipdb
- i've heard vscode has a good remote debug capability so that might be a way to jump into the debugger
- all the anvil server callbacks have a 30 second timeout
- so make sure you only try to debug in a anvil background task (or i think the timeout will stop you prematurely)

QUESTION
Graphical Least Absolute Shrinkage and Selection Operator, has been introduced by Jerome Friedman, Trevor Hastie and Robert Tibshirani ("Sparse inverse covariance estimation with the graphical lasso",2014). They suggest the block coordinate-descent algorithm for the problem solution (see. "The Graphical Lasso: New Insights and Alternatives" by Rahul Mazumder and Trevor Hastie). I wrote this easy MATLAB code using CVX, given X
(regressor's matrix of size m,n
):

- There is a unique solution (which should be true if your objective is regularized, which it appears to be by the last term.)
- There are no bugs in either implementation.
Both implementations should return the exact same solution as the problem is a convex semidefinite program. The difference you should observe is
- Runtime, one will likely run longer than the other, I would bet your implementation uses a general-purpose solver package (CVX) so should be slower.
- Memory usage, once again, I would expect the general purpose (unutuned) package should consume more memory.
- Numerical stability, in general this some implementations will be much more numerically stable. That is, if you use a weak regularization (very small lambda) you may find that some implementations fail to converge while others still work.
For small and toy problems this should not be a big deal (which is usually the case if you are an academic.) If you are a person trying to do something useful in the real world, runtime & memory usage tend to be extremely important, as they control what size problems you can tackle with your approach.
The only way to know the relative limitations to each approach is to implement and try both! At the very least, I would implement and run both approaches as a sanity check that both implementations are likely correct (the chance of both implementations being incorrect and reporting the same results across a range on inputs is very low.)
QUESTION
I've created a random database of 100 soccer players, with randomly generated names, positions, and ability (1-5). I want to append the list so that it reviews the ability of each player and assigns a value (20-100) based on their ability. 1 ability = 20 value. 2=40, 3=60, 4=80, and 5=100. In excel, for example, I would do a vlookup to the ability (1-5) and apply the value based upon the ability number. How would I go about doing this in a Python list? Thanks
