converting rsf to numpy array

[tgautam03]

I am trying to convert amoco velocity model to numpy array but I am getting error :

Traceback (most recent call last):
File "model.py", line 4, in
inp = m8r.Input("vel.rsf")
File "/home/atom/rsf2.0/lib/python2.7/dist-packages/m8r.py", line 715, in init
self.__create_variable_dictionary(self.header)
File "/home/atom/rsf2.0/lib/python2.7/dist-packages/m8r.py", line 791, in __create_variable_dictionary
if rhs[0] in (squot, dquot):
IndexError: string index out of range

when I am running the following code

import m8r
import numpy as np
import matplotlib.pyplot as plt
inp = m8r.Input("vel.rsf")
n1 = inp.int("n1")
n2 = inp.int("n2")
 
data =inp.read(shape=(n2,n1))
data = data.transpose() # Example of numpy in action
print("SHAPE OF ARRAY : ", data.shape)
print("MAX VEL : ", np.max(data))
print("MIN VEL : ", np.min(data))
#print("UNIQUE VELS : ", np.unique(data))
np.save('pvel.npy', data)
plt.imshow(data)
plt.show()

Here is my code for the SConstruct file

from rsf.proj import *

Fetch('velmodel.hh','Amoco')

Flow('vel','velmodel.hh',
	'''
	dd form=native | scale rscale=0.001 |
     	put label1=Depth  unit1=km label2=Lateral unit2=km
	''')
Plot('vel',
	'''
	grey color=j mean=y title="Amoco model" 
	scalebar=y bartype=v barlabel="V" 
	barunit="km/s" screenratio=0.45 color=j labelsz=10 titlesz=12
	''')

End()

@zhichenggeng I updated m8r.py as you have mentioned but now I am geeting this error :

Traceback (most recent call last):
File "model.py", line 4, in
inp = m8r.Input("/home/atom/work/github/mdg/madagascar/2D_modeling/amoco/vel.rsf")
File "/home/atom/rsf2.0/lib/python2.7/dist-packages/m8r.py", line 720, in init
self.f = open(self.filename,'r')
FileNotFoundError: [Errno 2] No such file or directory: '"/var/tmp/madagascar/2D_modeling/amoco/vel.rsf@"'

Earlier the same code worked for marmousi model but after updating there's same error on that code as well.
