I using the mac os and thonny micropython ide.
the file is called graph.txt on the desktop.
when i try reading it from the micropython ide, it gives the error:
file = open("graph.txt")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
OSError: [Errno 2] ENOENT
when i try with the full file path it obviously still gives the same error. and when i write a new file, it is always empty and is not linked to the external files.
im expecting to cast the list inside the text file into a variable for my program to use.

I'm on MacOS Big Sur trying to run rfcat. I am running anaconda as well and I have set up an environment with Python2.7 when I originally got errors with Python3.x. I have downloaded the pyusb, pyreadline, ipython, PySide2, and the libusb dependancies. Libusb seems to be giving me the most trouble. I keep getting the following error:
Error in resetup():NoBackendError('No backend available',)
Error in resetup():NoBackendError('No backend available',)
Error in resetup():NoBackendError('No backend available',)

From my research so far, backend is how pyusb refers to libusb, libusb1 or openusb. It is unable to find the libusb within the environment. I did a little tracking and found that ultimately, the find_library() function is found in ctypes in util.py. It refers to the executable path for MacOS with #executable_path/../lib/libusb%s..... I tried to put libusb into a folder on my executable path to hopefully match this functions search, and still got the same errors. I then found instructions on inputting a custom path for the backend for pyusb here. This appears to be a method where you input the device and backend information at the beginning of your program. The code I inserted is as follows:
import usb.core
import usb.backend.libusb1 as libusb1
backend = libusb1.get_backend(find_library=lambda x: "/path/to/file/lib/libusb-1.0.0.dylib")
dev = usb.core.find(idVendor=“MyVID”, idProduct=“MyPID”, backend=backend)
This induced a similar error but with a different traceback when I placed the code in rflib.init and the rfcat codes:

I have since reset things back to how I started and am still getting the original error listed above.
I think this largely has to do with the anaconda environment, which I can of course remove. I want to try to find a way to make this work though. Is there a better method to help rfcat find the libusb as required? Another possible solution is resolving the actual executable_path. Does anyone know how to find the executable_path?
In case it helps, I will list the default locations for commands and files.
rfcat: /opt/anaconda3/envs/rftools/lib/python2.7/site-packages/rfcat
pyusb: /opt/anaconda3/envs/rftools/lib/python2.7/site-packages/usb
ctypes: /opt/anaconda3/envs/rftools/lib/python2.7/ctypes
libusb: /opt/anaconda3/envs/rftools/lib/python2.7/site-packages/usb/lib

If you have Python 2.7 installed try opening the Google App Engine Launcher. Then Edit -> Preferences and check the correct python path is set.
If you installed Python on C:/ it should be something like:
C:\Python27\pythonw.exe
I'm trying to setup the chromium code following the documentation on Mac OS X 10.9.2.
I could successfully fetch the code with command:
fetch --nohooks chromium --nosvn=True
but when I try to sync the projects with gclient sync command it's breaking in the middle of the process throwing the following OSError:

It seems to me that it is complaining about os.link(tarinfo._link_target, target path), so I tried creating a link using that function which works fine.
Is there any other configuration that I need to take care of?
Thanks in advance!
I placed the chromium project on an external hard disk as you did, and I got the same error.
Perhaps you should try the syncing stuff in your internal drive.
Haven't tried. Hope that help.
I have been having all kinds of problems getting Windmill setup and installed. I thought I finally got it setup, but now when I try to just run windmill, I get the following errors. Any help is appreciated.

I had the same issue; Windmill doesn't work with Python 3.x. To fix the problem install Python 2.x
