[Python-es] TypeError: unhashable type

[Rolando Paz]

Hola a todos...

Alguien puede decirme de qué se trata este error?

rolando en rolando-MS-7815:~/ipoco-0.1.1$ plot_auto_arte.py
config_scripts/i4_c1024_arte.config

Parsing config file config_scripts/i4_c1024_arte.config...OK
Connecting to IBOB on port 23.
Connecting to IBOB on ip 169.254.128.32.
Grabbing spectrum number 1
Traceback (most recent call last):
  File "/usr/local/bin/plot_auto_arte.py", line 80, in updatefig
    self_reord.append (numpy.concatenate((inputs[input][512:1024],
inputs[input][0:512])))
TypeError: unhashable type

Estoy tratando de graficar unas señales en un rango de 0 a 1024 puntos en
el eje X.

Agradeceré cualquier sugerencia.

Saludos

RP
