Hello everyone.
I've installed the package with pip install roboticstoolbox-python and checked that all the dependencies have indeed been installed. Everything works fine until i try to use the Swift backend; this is what i got with the following bit of code:

import roboticstoolbox as rp

panda = rp.models.Panda()
panda.plot(q=panda.qr)

The web page (i've already tried to use different browsers and also clearing the cache) just shows the error ERR_EMPTY_RESPONSE. Does anyone have any idea on how to fix this?

Thank you in advance.

I am facing the same issue. I have installed roboticstoolbox with pip 21.3.1 for python 3.6.8 and I get exactly the same error messages. Is there already a solution for this?

Edit: with diving a bit in the code, I see that class MyHttpRequestHandler inherits http.server.SimpleHTTPRequestHander (SwiftRoute.py, line 222), in which the directory argument is added in python3.7. That means that the Swift library is not compatible with python3.6, or changes in the library have to be made.

I solved by upgrading to Python 3.9.

Hi Mattia, thanks for your reply! Indeed a solution, but unfortunately I need to run it on python3.6.
I solved it by implementing a directory parameter in the SimpleHTTPRequestHandler class from the http.server module. Not the correct way, but that's fine by me.

Hi, suitendall, i am facing the same issue, too, but i am new to ubuntu, can you tell me your specific solution? I'd appreciate it.
