EuroPython 2021: Opening our Merchandise Shop
We’re very happy to announce our merchandise shop for EuroPython 2021, with a fabulous new design for the attendee t-shirts: * EuroPython 2021 Merch Shop * https://ep2021.europython.eu/europython/europython-merchandise-shop/ You can find the shop under the "EuroPython" menu entry on the conference website. It is run on the Spreadshirt platform and so Spreadshirt will handle all payments, invoicing and shipping. We have preconfigured a large number of items in the shop based on the designs for EuroPython 2021, but you can also customize the looks by clicking on the editing pen on the product pages. Any profit this creates will go towards the EuroPython financial aid budget, so will be put to good use. Discounts - To make things a little easier for you, we have configured the following discounts Spreadshirt offers: - 20% off from July 8 - 11 - 15% off from July 12 - 15 - free shipping from July 16 - 19 Shipping worldwide -- Spreadshirt is shipping to a lot of destinations worldwide. Unfortunately, they don’t support shipping to the US, Australia, Brasil and a few other countries on their European shop system for tax reasons. If you'd like to order from one of those countries, perhaps you can find a friendly Pythonista who would be willing to forward you the merch from Europe. Quick Summary - EuroPython 2021 will be run online from July 26 - August 1: - Two workshop/training days (July 26 - 27) - Three conference days (July 28 - 30) - Two sprint days (July 31 - August 1) The sessions will be scheduled to ensure they are also accessible for those in the Asian and Americas time zones.

No, the way i have installed flask was under root account with the command pip3 install flask. But even if i installed flask under my nikos user account its evene worse as the file flask is not entered into PATH. So i guess as root i have to install flask, but then why cant it import 'run" ?

Hi Do you have a file or folder named 'flask' in the same directory as www.py by any chance?

Re: i just moved from bottleframework to flask. I changes what needed to be altered to convert the code and when i run it i just get "Internal server error" Running tail -f ../logs/error_log i get no
[my reply on the list this time :)] That's fine. Sorry, I should have provided more information. This type of error that you're gettting /can/ happen if you have the library correctly installed, but within your project, you have a different file of the same name as the library. Then when python tries to import 'flask', it actually imports your local file, NOT the installed flask. You see the error message is *not* saying that python can't find flask, but that it can't find a name `run` within the flask module: from flask import run, route, request, redirect ImportError: cannot import name 'run' Therefore python has successfully found a module named flask somewhere, just that it's probably not the module you were expecting it to find. This is almost always because of the file name issue I mentioned above, OR because the wrong version of flask has been installed, or something similar. One thing to try would be at the *very* top of counters.py, add the following lines: import flask print(flask) then run your command again, and see what the stdout output is. You should see something like: Does XX look like the right place for the flask installation? if not, then that's the problem.

No, the way i have installed flask was under root account with the command pip3 install flask. But even if i installed flask under my nikos user account its evene worse as the file flask is not entered into PATH. So i guess as root i have to install flask, but then why cant it import 'run" ?
