Hello,

I have a Mac, OS 10.10 (Yosemite) running Python 3.4.4

When I try to read in a SEGY file using a simple python script, t.py:

import signal
import sys
from obspy import read, Trace, Stream, UTCDateTime
from obspy.core import AttribDict
from obspy.segy.segy import SEGYTraceHeader, SEGYBinaryFileHeader
from obspy.segy.core import readSEGY
import numpy as np
fin=readSEGY('/Users/goldman/dimond15.11.segy’)

I get the error message:

Traceback (most recent call last):
  File "t.py", line 9, in <module>
    fin=readSEGY('/Users/goldman/dimond15.11.segy')
  File "/opt/local/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages/obspy/segy/core.py", line 245, in readSEGY
    second=second)
  File "/opt/local/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages/obspy/core/utcdatetime.py", line 330, in __init__
    dt = datetime.datetime(*args, **kwargs)

Does this mean there is a bug in readSEGY?

Note that if I try to run t.py in an anaconda environment:
cd ~/anaconda/bin
sh
conda create -n myenv
conda install -n myenv -c -obspy obspy
source ./activate myenv
python t.py

Then I get a lot of inscrutable error messages:

Traceback (most recent call last):
  File "t.py", line 3, in <module>
    from obspy import read, Trace, Stream, UTCDateTime
  File "/Users/goldman/anaconda/envs/myenv/lib/python3.4/site-packages/obspy-0.10.2-py3.4-macosx-10.5-x86_64.egg/obspy/__init__.py", line 47, in <module>

  File "/Users/goldman/anaconda/envs/myenv/lib/python3.4/site-packages/setuptools-19.1.1-py3.4.egg/pkg_resources/__init__.py", line 2379, in load
  File "/Users/goldman/anaconda/envs/myenv/lib/python3.4/site-packages/setuptools-19.1.1-py3.4.egg/pkg_resources/__init__.py", line 2396, in require
  File "/Users/goldman/anaconda/envs/myenv/lib/python3.4/site-packages/setuptools-19.1.1-py3.4.egg/pkg_resources/__init__.py", line 849, in resolve
pkg_resources.DistributionNotFound: The 'nose>=0.11.1' distribution was not found and is required by matplotlib

So I am at a loss
