AttributeError: SinusoidalVoltageSource

[joseph210385]

Environment (OS, Python version, PySpice version, simulator)

Win7 Python3.6.5 PySpice1.1.4

Expected Behaviour

it always return "AttributeError: SinusoidalVoltageSource"
When I trying to input ""source = circuit.SinusoidalVoltageSource('input', 'in', circuit.gnd, amplitude=amplitude, frequency=50)''

Actual Behaviour

Traceback (most recent call last):
File "ring-modulator.py", line 41, in
modulator = circuit.SinusoidalVoltageSource('modulator', 'in', circuit.gnd, amplitude=1@u_V, frequency=1@u_kHz)
File "D:\Python36\lib\site-packages\PySpice\Spice\Netlist.py", line 719, in getattr
raise AttributeError(attribute_name)
AttributeError: SinusoidalVoltageSource

Steps to reproduce the behaviour

How can I fix this? Thanks

I can confirm this bug with Arch Linux, Python 3.6.5 and PySpice 1.1.4.

$ python examples/filter/low-pass-rc-filter.py 
Traceback (most recent call last):
  File "/usr/lib/python3.6/site-packages/PySpice/Spice/Netlist.py", line 717, in __getattr__
    return self.__getitem__(attribute_name)
  File "/usr/lib/python3.6/site-packages/PySpice/Spice/Netlist.py", line 710, in __getitem__
    raise IndexError(attribute_name)
IndexError: SinusoidalVoltageSource

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "examples/filter/low-pass-rc-filter.py", line 26, in <module>

I ran into the same issue. With "modulator = circuit.Sinusoidal('modulator', 'in', circuit.gnd, amplitude=1@u_V, frequency=1@u_kHz)" it worked fine.

After looking into the code I found out that the problem is that the online documentation is for the current master branch in the repository which has some massive differences in the API from the most recent version in PyPI.

So ether install it from the git repository or don't use the online documentation.

Will upgrade package and doc

I'm trying to prove the examples in Docs, but when Execute the example low-pass-rc-filter.

I try putting this at the beginning but the error persists

I run following code and there is no output, looks " circuit.SinusoidalVoltageSource" does not work:

`import matplotlib.pyplot as plt

circuit = Circuit('Transistor')

circuit.V('power', 5, circuit.gnd, 15@u_V)
source = circuit.SinusoidalVoltageSource('in', 'in', circuit.gnd, amplitude=.5@u_V, frequency=1@u_kHz)
