There are many Python libraries called “snappy”, so care is needed to ensure that python loads the ESA SNAP version from ~/.snap/snap-python. Recent versions of macOS do provide zsh, which many consider an improvement over bash, but which may object to some bash scripts (the fixes are usually trivial).

I find users are often surprised when they don’t get the expected Python version.Īpple will not distribute a current bash version due to the license restrictions. It might be useful to have snappy-conf check that the python-path ends with a python program and display the startup header. This is because snappy-conf tried to execute the snappy directory as if it was a python program. Check that this path is working in the terminal. The “ path” should end with python, e.g., /opt/anaconda3/envs/sentinel/python. If you used the “ path” given below, that won’t work. If you installed using sudo you may encounter permission problems when configuring snappy or updating SNAP.

This banner should mention the version (3.6.x) and Anaconda.ĭid run run the installer using sudo? Some users use sudo to install SNAP in /Applications, others install to ~/Applications which does not require use of sudo. Python should give a banner and the python > prompt. There appear to be newer versions on conda-forge.

Some users have tried this but ended up with a very old Python-3.6.

Created an Anaconda virtual environment called sentinel with Python version 3.6.

Typo (JAVE -> JAVA)? Again, you should not do this until you have failed to get ESA SNAP snappy working with Python-3.6.

In Terminal, set JAVE_HOME variable to the following.

OpenJDK comes in two forms: the Java Runtime Environment (JRE) and the full Development Kit (OpenJDK JDK) which could be needed to buildĪ jpy for a Python version later than 3.6. Installing a JDK should be a last resort if you can’t get snappy to run with Anacoda3’s Python-3.6 environment. You have done a good job of describing what you have done, but there are a few details that need clarification. Apple has made changes to increase security of recent macOS versions so there could be some new issues, but I am familiar with some of the complexities of configuring ESA SNAP snappy on OlivierLej I did the following steps. I’m retired from a lab where macs were widely used, but don’t currently have access to macOS.

Running the same commands in Terminal hasn’t worked either. In the last setup page, I tried to configure my python installation to use Snappy by checking the tickbox and proving the path to my “sentinel” virtual environment, but ran into the following error:

Installed the SNAP software tool (version 8.0.0) found at.

I’ve spent several hours trying to install the Python Snappy library on my Mac, but have run into issues.
