[SOLVED] lcapy in Jupyter Notebook

I want to draw a simple schematic with lcapy and have the following code:

from lcapy import Circuit
cct = Circuit("""
V 1 0 {V(s)}; down
R 1 2; right
C 2 _0_2; down
W 0 _0_2; right
""")
cct.draw('schematic.pdf')

I have installed lcapy via pip, this works just fine. But I am not able to draw my desired circuit, because of following errors:

TypeError
Traceback (most recent call last)
<ipython-input-6-51c0bd8d637b> in <module>
      6 W 0 _0_2; right
      7 """)
----> 8 cct.draw('schematic.pdf')

TypeError: Unknown setting 'ln_notation'.

I dont really know what to do because this is my first time using lcapy.

Thanks in advance!

TypeError: invalid input: V(s)
