Hello,

I am running a Mac OS 10.10.5 (Yosemite)

When I run the following, I get a checksum error:

sudo port install py-obspy-devel

I have already tried:
sudo port self update
sudo port clean —dist py-obspy-devel

but it does not help

Thanks,

Hi Mark,

if there is no specific reason why you need it in an existing Python
environment of your system, the easiest and cleanest installation in
almost all cases is to set up a fresh, independent Python environment
with Anaconda, see
https://github.com/obspy/obspy/wiki/Installation-via-Anaconda.

cheers,
Tobias

Thanks Tobias

I installed anaconda, then typed, in the ~/anaconda/bin directory:

conda create -n myenv python=3.4
source ./activate myenv
conda install -n myenv -c obspy obspy

then I try to run the following python script:

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’)

and all I get are a bunch of inscrutable errors:

(myenv)sh-3.2$ python t.py

any suggestions? Is OBSPY compatible with anaconda on a Mac Yosemite OS 10.10?

Hi Tobias

If I try to run obspy outside of Anaconda, using python 3.4.4, and running the t.py python script:

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
import sys

I get the error message:

[goldman] python t.py

Traceback (most recent call last):
  File "t.py", line 11, 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)
TypeError: Required argument 'month' (pos 2) not found

which make me think there is a bug in OBSPY’s readSEGY function
