Installer issue with version 1.0 #83

Closed Patrick-Cole closed 5 years ago

Patrick-Cole commented 5 years ago

Hi,

I am using winpython (https://winpython.github.io/) and install missing packages from (https://www.lfd.uci.edu/~gohlke/pythonlibs/). Winpython uses pip to install packages, although there is a nice GUI for this. There is no problem with the initial install, but when importing mtpy I get the following:

GDAL_DATA environment variable is not set Please see https://trac.osgeo.org/gdal/wiki/FAQInstallationAndBuilding#HowtosetGDAL_DATAvariable Ignore GDAL as it is not working. Will use pyproj Traceback (most recent call last):

File "", line 1, in import mtpy

File "C:\Python\WPy64-3730b2\python-3.7.3.amd64\lib\site-packages\mtpy-1.0.2-py3.7.egg\mtpy__init__.py", line 3, in from mtpy.utils.mtpylog import MtPyLog

File "C:\Python\WPy64-3730b2\python-3.7.3.amd64\lib\site-packages\mtpy-1.0.2-py3.7.egg\mtpy\utils__init__.py", line 51, in EPSG_DICT = np.load(epsg_dict_fn, allow_pickle=True).item()

File "C:\Python\WPy64-3730b2\python-3.7.3.amd64\lib\site-packages\numpy\lib\npyio.py", line 422, in load fid = open(os_fspath(file), "rb")

FileNotFoundError: [Errno 2] No such file or directory: 'C:\Python\WPy64-3730b2\python-3.7.3.amd64\lib\site-packages\mtpy-1.0.2-py3.7.egg\mtpy\utils\epsg.npy'

There are two problems from me here: 1) It does not see the GDAL_DATA. Under my install, this is easily solved by importing gdal (which seems to set this environment variable) 2) It does not find 'epsg.npy'. I fixed this by copying the relevant file from the original .zip file but I have no idea if there are any other data files missing. I suspect that this might be able to be fixed with a tweak to setup.py.

I can get this bug by installing via pip, or by using 'python setup.py install'

Winpython is a windows python distribution. I run it on a windows machine with windows 7. I have all the dependencies installed.

Please let me know if I did something wrong or what can be done.

Hi Patrick, thanks for logging the issue details. You are right that the 'epsg.npy' need to exist in the relevant dir. And this is the only data file I am aware needing to be handled.
For GDAL to function, it must be installed correctly and with GDAL_DATA env variable configured.

Thanks for the response! I can manually copy the epsg.npy file for now, so I should be fine. Your confirmation that this is the only file affected helps me a great deal.

I suspect that my GDAL issue is unique to Winpython. Winpython is a portable distribution which does not (by default) register anything in the registry. I guess thats why (in my case) all I need to do it import gdal once (before mtpy), and upon doing so GDAL_DATA env variable suddenly is configured. I therefore have a solution to this as well.

Thanks for your help!

Hi,

I am closing this since it it no longer an issue with version 1.1.3. Thanks for your work!
