I have imported ecoinvent 3.7.1 on a brightway project and i followed a few tutorials to understand brightway set up procedures and usage.

I want to use brightway to perform calculations on the inventory data of some processes (in particular i want to sum all emissions to air of CO2, CH4, N2O.

I tried with:

I'm trying to build a very basic app that uses PyQt5 on Big Sur.

Using the latest dev version of pyinstaller I build the app without errors but, when I launch it, it crashes immediately after starting. Launching the exec, I get segmentation fault right after app = QApplication(sys.argv).

Here's my configuration:

In my attempt to write an authenticated Servant API where handlers use the RIO monad instead of Servant's own Handler monad, I am stuck on authenticated routes that return no content; i.e., Servant's NoContent type. When I try to hoist the RIO server into the Handler using hoistServerWithContext, I get a type error that I don't grok.

Here is the simplified API and server setup:

I'm trying to combine Servant authentication (servant-auth-server package) with RIO as my handler monad to avoid the ExceptT anti-pattern. However, I can't line up the types properly for handling denied authentications.

My (simplified) API endpoint is

I have a 3 deep array. Currently, the code will isolate a record based on one field ($profcode) and show the heading. Eventually, I am going to build a table showing the information from all the other fields. The code so far is using in_array and a function that accepts $profcode. I am unsure if (and how) I need to use array_keys() to do the next part when I retrieve the "Skills" field. I tried:

Little known feature of C++ is ref-qualifiers for member functions.

It works as I expect it to work in most cases, but it seems that std::optional does not forward the knowledge of its imminent demise to contained object member functions. For example consider the following code:

i'm working on an nlp project and trying to follow this tutorial https://medium.com/@ageitgey/natural-language-processing-is-fun-9a0bff37854e and while executing this part

The users can execute my Python app in directories containing their own Python scripts. If any of these scripts has name which clashes with a library module used by my program (or even clashes with the name of my module), everything breaks with an unhelpful error message.

I know that Python (since 3.4) has -I switch, which makes import machinery ignore current directory (ie. "" won't be added to sys.path). This would almost solve my problem, but it has the side effect of also ignoring user site packages.

I know I can tweak sys.path after my program has loaded, but it won't help if the user (by accident) shadows the main module of my program.

Can I somehow make Python ignore current directory but give me user site packages at the same time?
