Error in calc_uca()

[tzoiker]

When I try to run calc_uca, I get the following error:

pydem/cyfuncs/cyutils.pyx in pydem.cyfuncs.cyutils.drain_area (/private/var/folders/1j/r_xd9vp15td_mdt_3rgrx13w0000gp/T/pip-rmLTHG-build/pydem/cyfuncs/cyutils.cpp:2470)() ValueError: Item size of buffer (8 bytes) does not match size of 'int' (4 bytes)

Installed pydem via pip install --ignore-installed git+git://github.com/creare-com/pydem.git@develop as in here https://github.com/creare-com/pydem/issues/7 to solve the same problem: TypeError: Cannot cast ufunc add output from dtype('float64') to dtype('bool') with casting rule 'same_kind'.

Python 2.7.12, MacOS 10.12.3, 64-bit.

Note: GeoTIFFs I provide as an input are of float32 type, but calc_slopes_directions outputs float64.

What version of numpy are you using?

[tzoiker]

@mpu-creare, 1.13.0

[mpu-creare]

Okay, I'll have a look. Little swamped over here, it may take a few weeks. There are a couple of enhancements in the pipeline I haven't had a chance to push through. I'll lump that in the update that's coming.

[mpu-creare]

Actually, could also please copy the output from: pip install --ignore-installed git+git://github.com/creare-com/pydem.git@develop ?

Thanks.

@mpu-creare Thank you!

Output of pip install --ignore-installed git+git://github.com/creare-com/pydem.git@develop:

[mpu-creare]

Mmm... it doesn't look like cython was run when installing pydem... perhaps the old version of the binaries are being used (or perhaps the output is being suppressed on the MAC, I don't have a MAC immediately handy.)

Can you please try completely removing pydem and reinstalling? Please copy the output of the installation again.

[tzoiker]

@mpu-creare output is the same...

But now calc_uca() gives:

"pydem/cyfuncs/cyutils.pyx in pydem.cyfuncs.cyutils.drain_area (/private/var/folders/1j/r_xd9vp15td_mdt_3rgrx13w0000gp/T/pip-rmLTHG-build/pydem/cyfuncs/cyutils.cpp:2465)()

ValueError: Buffer has wrong number of dimensions (expected 1, got 2)"

UPD: OK, for some reason now it is the same error as the first one.

[mpu-creare]

@tzoiker any chance you can share your input data?

Incidentally, this is where I've tried to fix the problem in #5: https://github.com/creare-com/pydem/commit/311d2171f07ce1fe0955bff194bde573ec1e3d42 I'm not sure why it's showing up again. I also just did a fresh install on Windows using:

conda install gdal numpy scipy traits
pip install geopy
pip install --no-deps --ignore-installed git+git://github.com/creare-com/pydem.git@develop

And now running a calculation on an Nasa SRTM geotiff seems just fine... I am working on a new release as well...

[mpu-creare]

Ok, figured out how to reproduce the error. Working on it...

[mpu-creare]

Ok, think we finally solved it. Just pushed a new version of pydem. Let me know if the new version solves your problem.

[mpu-creare]

Closing this out.
