pyproj.Proj(..) raising RuntimeError: 'Invalid argument' about pyproj

[mtreiber]

I had the same issue and resolved it by installed the conda package from anaconda.org as follows:

conda install -c https://conda.anaconda.org/ioos pyproj

[joernu76]

I may have a related, new problem on Anaconda3 Windows with version 1.9.5.1-py36hb98d9bb_1
The value of pyproj.datadir.pyproj_datadir is

"C:/Users/icg174/Anaconda3\share\proj"

while the data is actually located in

C:/Users/icg174/Anaconda3/Library/share/

so both the formatting of the path seperators is off and the reference to the PROJ_DIR is missing as well as that there is a discrepancy between the listed and actual data path.

The last build version 1.9.5.1-py36_0 has the data files in a subdirectory of the package and also checks on the value of PROJ_DIR.

I ran into this problem in 64 bit Windows 10, Python 2.7. I had installed pyproj from the ioos channel as others have suggested and received version 1.9.4. This did not work for me - I got the same error mentioned in the original post.

I went with a different solution: upgrade pyproj to 1.9.5 using the .whl file available on Christoph Gohlke's website. It's not very neat, but it did the job.

I have the same problem for Proj and transform functions ! (same config as jorisvandenbossche btw)

[micahcochran]

Run this:

import pyproj, os.path
os.path.exists(pyproj.pyproj_datadir + '/epsg')

This returns True for mine, which works when I put in the offending epsg snippet.

What is the value of pyproj.pyproj_datadir? That is suppose to be the location of the epsg file (among others). If Proj.4 library can't find that file, it shouldn't work.

[johngonzalez]

How I get epsg dir?

[micahcochran]

epsg is a text file with PROJ.4 codes for projections. Here is the location of epsg on github folder for this project.

[jorisvandenbossche]

It returns False for me (tested in a fresh conda environment):

>>> import pyproj, os.path
>>> os.path.exists(pyproj.pyproj_datadir + '/epsg')
False

and it gives a strange value for pyproj_datadir:

>>> pyproj.pyproj_datadir
'C:\x07root\\stage\\Library\\share\\proj'

[jorisvandenbossche]

As I said in the original issue, I was able to get a working version on python 3.4 by downgrading to 1.9.3 and using the JimInCO channel for win64 (https://anaconda.org/JimInCO/pyproj). The output is then:

>>> import pyproj
>>> pyproj.__version__
'1.9.3'
>>> pyproj.Proj('+init=epsg:4326 +no_defs=True')
<pyproj.Proj object at 0x00000000020A9348>
>>> import pyproj, os.path
>>> os.path.exists(pyproj.pyproj_datadir + '/epsg')
True
>>> pyproj.pyproj_datadir
'C:\\Anaconda\\envs\\test_pyproj_py3\\lib\\site-packages\\pyproj\\data'

(but using pyproj 1.9.4 of that channel leads to the same error as the pyproj version from the default anaconda channel, so it seems a problem with version 1.9.4)

[bidhya]

Using the following install for windows with 32-bit python 2.7 solved my problem too

conda install -c https://conda.anaconda.org/ioos pyproj

[slava-kerner]

Another option is adding environment variable 'PROJ_DIR', set to position of pyproj\data (where the 'epsg' file resides), i.e. \Anaconda2\Lib\site-packages\pyproj\data (and, possibly, restarting to update env. vars).
After that running 'print pyproj.pyproj_datadir' shold give correct location, and 'os.path.exists(pyproj.pyproj_datadir + '/epsg')' should return true.

[jrovegno]

I had upgraded pyproj to 1.9.5.1 using conda default channel, problem solved on windows.

[tomalrussell]

I think can replicate what @joernu76 describes, with miniconda on Windows:

pyproj                    1.9.5.1          py36haf3c679_3    conda-forge

Copying the files from ...\Library\share to ...\share\proj as a workaround seems to fix my install.

[burcukolbay]

@joernu76 , @tomalrussell
The value of pyproj.datadir.pyproj_datadir is ...\share\proj. However, the problem is that I do not have "proj" in "/share". My files are in "...\Library\share" like in your case. Any idea how to fix it?

[sigbikes]

I can confirm that the problem still exists. I simply took the entire contents of Library\share and put them in \share\proj (which I had to create) and everything was right as rain. I would like to know what the contents of \proj\ look like so I can delete out the extraneous files though.

[Sieboldianus]

Perhaps this is related: I get the same error for pyproj 1.9.6, my pyproj.datadir.pyproj_datadir shows an empty string (Windows). However, as suggested here if I do conda uninstall pyproj and install with pip install pyproj, it works.

[deshmukhps95]

set the project lib path to the share folder of the conda environment:
import os
os.environ['PROJ_LIB'] =r'C:\Users{usename}\AppData\Local\Continuum\anaconda3\envs{conda_environment_name}\Library\share';

[snowman2]

Can you try the most recent version of pyproj (>=2.1.0) and check if this issue persists?

[Sieboldianus]

At least for me: my problem was related to using MingW64 Console under Windows 7 - this does not work with the conda-forge pypi feedstock (but doesn't affect the pip-package approach)

[snowman2]

Related to #216

[fasvello]

My solution:
I edited line 152 of ...site-packages/mpl_toolkits/basemap/init.py
replaced pyproj_datadir = os.eviron['PROJ_LIB'] with
pyproj_datadir = '/home/user/anaconda3/lib/python3.7/site-packages/pyproj'

Worked for me!
