Error while opening python plotting Editor.

i am getting the problem on pressing the 'Simulation' icon it says "Error while opening python plotting Editor." i have given field values also.I have followed all the instructions in the manual.

I am getting the errors like this

[INFO]: Ngspice simulation is called : /home/eswecha/eSim-Workspace/projrc

[INFO]: PythonPlotting is called : /home/eswecha/eSim-Workspace/projrc

[ERROR]: Exception Message :[Errno 2] No such file or directory: '/home/eswecha/eSim-Workspace/projrc/plot_data_i.txt'

[ERROR]: Exception Message :local variable 'alli' referenced before assignment

[ERROR]: Exception generated : [Errno 2] No such file or directory: '/home/eswecha/eSim-Workspace/projrc/plot_data_v.txt'.

I have followed all the instructions in the manual.

The .cir file is as follows

* /home/eswecha/eSim-Workspace/projrc/projrc.cir

* EESchema Netlist Version 1.1 (Spice format) creation date: Thu Feb 4 15:57:42 201

* To exclude a component from the Spice Netlist add [Spice_Netlist_Enabled] user FIELD set to: N

* To reorder the component spice node sequence add [Spice_Node_Sequence] user FIELD and define sequence: 2,1,0

* Sheet Name: /

R1 in out 1k\\t\\t

C1 out GND 1u\\t\\t

v1 in GND sine\\t\\t


and the .cir.out file is as follows

* /home/eswecha/esim-workspace/projrc/projrc.cir

v1 in gnd ac 2 0

r1 in out 1k

c1 out gnd 1u

.tran 0e-00 0e-00 0e-00

* Control Statements



print allv > plot_data_v.txt

print alli > plot_data_i.txt

Dear Yogi,

Please give transient analysis as start time = 0ms, increment = 10ms and stop time = 100ms.
