Python API, 'xdr_float' file reading problem. SWIG problem?

[pplotn]

Hello, all.
I have problems reading marmousi model:
File "/home/plotnips/Madagascar/lib/python2.7/dist-packages/m8r.py", line 765, in init
sys.stderr.write('filename=%s.\n',self.filename)
TypeError: write() takes exactly one argument (2 given)

I think this is related to swig installation or Python2/Python3 compatibility. Can you help with this problem? Or maybe there are some related issues, but I have not found anyone.
I installed swig of version 3.0.12. It was detected in config.py file:
SWIG = u'/usr/bin/swig'

marmvel.hh:
in="stdin"
esize=4 type=float form=xdr
n1=751 d1=4 o1=0 label1="meters"
n2=2301 d2=4 o2=0 label2="meters"
n3=1 d3=1 o3=0 label3=""
n4=1 d4=1 o4=0 label4=""
1728051 elements 6912204 bytes

CODE:
import numpy
import m8r as sf
model_input="marmvel.hh"
model_orig = sf.Input(model_input)
vel = model_orig.read()

/home/plotnips/anaconda3/envs/tensorflow_env/bin/python /home/plotnips/Dropbox/Log_extrapolation/scripts/deeplogs-master/data/test2.py
error reading from input file.
data_format=xdr_float

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

Process finished with exit code 1

Junwei,
It looks like Python cannot find the blas library. You may want to check
the LD_LIBRARY_PATH environmental variable and to set it to include the
path to libblas.
