miniconda install about gprmax

[craig-warren]

Glad you like it! We are slowly working towards a smoother install process.

Can you remind me what platform you are on? Presumably you are following the developer route so have compiled the Cython extensions? or have you downloaded the pre-built extensions for your platform?

[ELEGER]

Hey,

I just get the last gprmax-master.zip, conda env create -f conda_env.yml it and activate it.
Trying to get it build on a cluster, ubuntu64bits

cheers

[craig-warren]

OK, so follow step 4 to build the Cython extensions and you should be good to go. The gcc (the C compiler with OpenMP support) should already be installed on Ubuntu.

[ELEGER]

yeah, but still not:

To activate this environment, use:

$ source activate gprMax

To deactivate this environment, use:

$ source deactivate

[eleger@n0001 gprMax-master]$ source activate gprMax
discarding /global/home/users/eleger/miniconda3/bin from PATH
prepending /global/home/users/eleger/miniconda3/envs/gprMax/bin to PATH
(gprMax)[eleger@n0001 gprMax-master]$ python -m gprMax user_models/cylinder_Ascan_2D.in

ImportError: No module named 'gprMax.fields_update'

I'd say this is because I'm loading python3.2 (not 3.5) on the cluster could it be because of that ?

cheers

[craig-warren]

From the traceback you have Python 3.5. Did you follow step 4, i.e. compile the Cython extensions?

[ELEGER]

No, since I was building the endusers version.
Trying to compile the cython yields:
python setup.py build_ext --inplace
Traceback (most recent call last):
File "setup.py", line 37, in
open(os.path.join(packagename, 'gprMax.py')).read(),

UnicodeDecodeError: 'ascii' codec can't decode byte 0xc2 in position 8733: ordinal not in range(128)

Thanks

Hello,
Facing a similar issue.
PFA screenshot of the error.
miniconda and gprMax installs were absolutely fine. But not able to simulate the sample Ascan.

Thank You

Hi NishanthBhonsle,

I think your issue is different. Can you confirm a few facts:

• What version of Windows are you using? Is it 32- or 64-bit?
• Have you copied the compiled Python extensions into the gprMax-v.3.0.0b18/gprMax directory? This was part of step 1. Get the code
• Can you post a listing of the gprMax-v.3.0.0b18/gprMax directory?

[NishanthBhonsle]

• I am using windows 8.1 64-bit version.
• Yes i have copied the extensions into the gprMax-v.3.0.0b18/gprMax directory.
  PFA Screenshot of the directory.
  

In addition to these there are the following files

• yee_cell_build.pyx
• yee_cell_setget_rigid.cp35-win_amd64.pyd
• yee_cell_setget_rigid.pxd
• yee_cell_setget_rigid.pyx

Thank You.

@NishanthBhonsle I think Windows users may still have to install the Microsoft Visual Studio 2015 C++ Redistributable (vc_redist.x64.exe for 64-bit) from https://www.microsoft.com/en-us/download/details.aspx?id=48145. Can you give that a try and let me know if that solves it.

@ELEGER I think I've fixed the issue you were having. It was to do with reading the version number. The fix is in the master branch, and I'll make a new release tomorrow.

[ELEGER]

Good job Craig,
Pulled the latest dev version and everything worked smoothly.
Thanks for you help (quick, efficient and clever), and I'm glad I could help to find a small bug.

@NishanthBhonsle Did installing the Microsoft Visual Studio 2015 C++ Redistributable solve the problem for you?

[NishanthBhonsle]

@craig-warren Was unable to download Microsoft Visual Studio 2015 C++ Redistributable due to various reasons.
So using GprMax on linux platform and it is working perfectly.
Thanks a lot and will update you if I am able to get Visual Studio on windows.

[craig-warren]

OK, thanks. From my testing it should work with the Redistributable installed on Windows. I'll close this issue for now, but if you come back to Windows and can't get it working then please open this issue up again.
