No module named cartridge

[RobListon]

I'm trying to run stratasys-cli.py to read the info on a cartridge I dumped but I'm running into a problem. The command I'm running is "python3 ./stratasys-cli.py eeprom -t prodigy -e b60000014b406523 -i ~/eeprom-2365404b010000b6.bin" and this is the error: Traceback (most recent call last): File "./stratasys-cli.py", line 36, in from stratasys import manager File "/home/pi/stratasys/stratasys/manager.py", line 29, in import cartridge ImportError: No module named cartridge

Rob,

I'm just about to do the same....

With regards to "cartridge", I have the DS2433 EEPROM board from the cartridge and have wired directly. I have never seen a cartridge, and how it connects. I'm assuming there shouldn't be any issues?

I have noticed your post says Python 3, I did read somewhere on this forum that the code only supports Python 2 (from my understanding).

I have a quick question, regarding the pycrypto, where does it need to live?

Regards,

I installed Raspian via the NOOBS installer so I only had python 2.7.3 which caused a bunch of problems. I downloaded and installed python 2.7.9 from the source package to resolve those issues. As for pycrypto, I just downloaded that from https://www.dlitz.net/software/pycrypto/ then unpacked it and ran "python setup.py build" and "sudo python setup.py install" to install it.

Hi, thanks for the info. I too used NOOBS installer and installed Raspian. I'll check what version of Python i'm running. As for pycrypto, i did the same: build / install, but got errors.

I thought all this was going to be straight forward, but it's proving to be very character building!

I've put a post on pycrypto to see if i get any info back.

pi@raspberrypi ~ $ python --version Python 2.7.3

Think I need to upgrade.

After installing Python 2.7.9 all of the strange messages I was getting went away. I also tested using 2.7.6 on another computer. As far as I can tell, as long as you have 2.7.6 or higher you should be fine. Once you upgrade you'll probably need to install pycrypto again as well.

Rob,

I have python 2.7.9 and pycrypto now installed.

I'm now running the stratasys-cli command and getting an error, did you resolve your problem?

index out of range.... :(

Duplicate from the other issue you filled?

My problem was solved by not using Python3 and making sure I had python at version 2.7.6 or higher. Also, I needed python-dev installed to build pycrypto.
