I have written a small python script to read data from a digital thermometer, and everything works just fine in my computer. however, i need to run this same script in other systems, but i keep getting a "[Errno 10060] Operation timed out" error.
in the second computer i can see the device, it's endpoints and everything, but it's when i try to read from it that i'm getting the error.
this is the code (i intentionally did not set the configuration for the device, as i'm trying to speed up the reading, and in my system it proved not to be necessary):
import usb.core
def get_temp(T):
# find our device
dev = usb.core.find(idVendor=0x04d9, idProduct=0xe000)
# was it found?
if dev is None:
raise ValueError('Device not found')
# poll the thermometer for current temperature
t = dev.read(0x83, 32) # gets 32 bytes from ENDPOINT address 0x83
so, in the computer where i wrote this, it works as expected, and it returns a nice 32-byte array. but in other systems, i got the error:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>

i tried also setting device configuration this time, but still same error.
any ideas on what i might be missing?
edit: this is my output log with PYUSB_DEBUG environment variable set to debug:

I have a script:
if (enviar_ftp(mounted_usb) >= 0): # ML: enviar_ftp()->enviar_ftp(ser)
# Se agrega la captura de schedule online
s = get_schedule_online(get_id())
log("Programa en servidor: {0}".format(s))
if (s != ""):
save_programa(s)
enviar_situacion(get_id(), get_programa(), get_free_space()[3], 0, 0, str(100-int(get_free_space()[4])), battery_status(voltaje), voltaje, 0, 0)
# ser_write("<txt>\n")
else:
log('enviar_ftp() failed') # ser_write("<txn>\n")
Works fine in python2 but in python3 I get:

Any ideas?
Expect the script to work!!
I'm working on a project, using openmodelica. I'm trying to simulate the system multiple times and i wrote a python script to automatize it. I also override parameters on each iteration of the simulation, but if i try to override an array i'll get this on console:
Traceback (most recent call last):
File "pythonScripts/testing.py", line 164, in <module>
startSimulation(5,2,1,4, noFault,flyZone[1])

raise exc.with_traceback(None)
pyparsing.exceptions.ParseException: Expected end of text, found '(' (at char 4), (line:1, col:5)
This is an example of how i did it:
def startSimulation(n, intr, miss, statObs, fault, flyZone):
with open("newValues.txt", 'wt') as f:
f.write("const.N="+str(n)+"\n")
f.write("const.nIntr="+str(intr)+"\n")
f.write("const.nRocket="+str(miss)+"\n")
f.write("const.nStatObs="+str(statObs)+"\n")
f.write("fault.transMatrix[4,4]="+str(fault)+"\n")
f.write("const.flyZone[3]="+flyZone+"\n")
f.flush()
os.fsync(f)
os.system("./System -overrideFile=newValues.txt >> LogOverride")
noFault = "[1, 0, 0, 0; 1, 0, 0, 0; 1, 0, 0, 0; 1, 0, 0, 0]"
flyZone = ["{100,100,100}","{150,150,150}","{200,200,200}"]
startSimulation(5,2,1,4, noFault,flyZone[1])
Any suggestion?
OpenModelica will expand arrays into scalars when the C code is generated so you need to override each of the array elements separately in newValues.txt:
fault.transMatrix[1,1]=1
fault.transMatrix[1,2]=0
fault.transMatrix[1,3]=0
fault.transMatrix[1,4]=0
fault.transMatrix[2,1]=1
fault.transMatrix[2,2]=0
fault.transMatrix[2,3]=0
fault.transMatrix[2,4]=0

/ is the division operator. If the divisor is zero, you will get an exception.
Very likely you tried to access an element of the grid. If board is a list of lists, you must use the subscription operator twice in a row. Since the grid is organized in rows, the first subscription index is y and the second is x:
if board[x / y]==0:
if board[y][x]==0:

After reading my data, I use to following script:
for sample in record.samples:
print(type(sample))
I get:

I am trying to write the output to a file using:
output.write("{}\t{}\t{}\t{}\t{}"
.format(contig1, pos1, ref_allele1, all_alleles1, all_freq1))
for sample in record.samples:
output.write("\t{}\t{}".format(sample['GT'], sample['PI']))
Everything is working well, but I have some line that have PI field missing - which means PI is totally missing and is not (PI = None). When my script hists that line I get AttributeError:

How, can I set the PI value to period (.) when it is not in my data (record.sample)?
I tried several method. One of method I though would work is:
output.write("\t{}\t{}".format(sample['GT'] or None, sample['PI'] or None))
But, still failing.
Any, suggestions.
Thanks,
You can try sample.get('PI') or '.'.
Get returns by default None, when a key is not defined.
