Undefined symbol: proj_context_set_autoclose_database

In trying to install and work with sentinelhub there is a dependency to pyproj package. Any tips to what could be going wrong with pyproj

from pyproj import _datadir
ImportError: lib/python3.6/site-packages/pyproj-2.6.0-py3.6-linux-ppc64le.egg/pyproj/_datadir.cpython-36m-powerpc64le-linux-gnu.so: undefined symbol: proj_context_set_autoclose_database

from sentinelhub.common import BBox, CRS

Can you provide:

Installation method/steps

• Installation method (conda, pip wheel, from source, etc...)
• How did you install PROJ? Where is it installed?
• Please provide all commands/steps you used to install pyproj and PROJ.

Environment Information

• pyproj version you are attempting to install
• PROJ version (Execute proj command and give version here.)
• Python version (python -c "import sys; print(sys.version.replace('\n', ' '))")
• Operation System Information (python -c "import platform; print(platform.platform())")

[Nqabz]

Installation and environment information are as follows:

PROJ installation

• conda install -c anaconda proj
• conda install -c conda-forge proj-data

Pyproj installation

• export CC=gcc
• pip install pyproj

SENTINELHUB Installed from source

• tar -xzvf sentinelhub-3.0.2.tar.gz
• cd sentinelhub-3.0.2/
• python3 setup.py build
• python3 setup.py install

All installed in a Conda environment. Environment information:

• PROJ: Rel. 7.0.0, March 1st, 2020
• Python: 3.6.10 |Anaconda, Inc.| (default, Jan 7 2020, 21:47:07) [GCC 7.3.0]
• Operating system: Linux-4.14.0-115.14.1.el7a.ppc64le-ppc64le-with-redhat-7.6-Maipo

I think the issue is likely mixing where you are installing PROJ from. With your current method, you are getting two different versions of PROJ.

I would recommend instead of:

conda install -c anaconda proj
conda install -c conda-forge proj-data
pip install pyproj

To just do:
conda install -c conda-forge proj-data pyproj

Great, I uninstalled and ran as above and that got me past the previous issue. However this I hit
this new issue:

>>> import pyproj
>>> 
>>> pyproj.CRS(4326)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: module 'pyproj' has no attribute 'CRS'
>>> 

This is pyproj version 1.9.5.1

[snowman2]

This is pyproj version 1.9.5.1

The CRS class only exists in pyproj>=2

I should have paid more attention to what is available and in what package. Thank you!

Not a problem 👍
