It says it cannot find Python home: /System/Library/Frameworks/Python.framework/Versions/Current/lib/python2.7.dylib/python37

Previous version scripts work fine. Any idea how I could fix this?

Hi Chris,

Hope you are doing well.
I had the same issue when using the latest version: 1.2.20211006 on my mac big Sur 11.5.2.
"Unable to find Python home: /System/Library/Frameworks/Python.framework/Versions/Current/lib/libpython2.7.dylib/python37"

One thing that may be related, when I type "which python" in terminal, i got
which python

Could you give me some advice on this? Thanks

3. The previous version (v1.2.20210824) works fine. I'll continue to use this version for now.

I have created a new issue

Unfortunately, I can not replicate this issue on my system. Can you try these two methods in sequence to see if they resolve your issue:

1. Install the v1.2.20211007 .dmg 
 
https://github.com/rordenlab/MRIcroGL/re...

2. If this fails, does launching the application from the terminal command line with the "-r" argument resolve the issue? This varies depending on your installation location, but for most users it is:

/Applications/MRIcroGL.app/Contents/MacOS/MRIcroGL -r

Hi Chris, 

I have installed the version (v1.2.20211007) that you pointed to and it works perfectly now!
Thanks!

Best,
Chuanji

Hi Chris,

Thanks for your help. v1.2.20211007 seems to work fine.

Best wishes,

Sam

OK, I have upgraded the macOS package hosted on NITRC to include this fix. This support will also be part fo future releases.

Hi Chris,

I seem to be having a similar issue, but with Linux (Ubuntu 18.04.6 LTS), when trying to use the template scripts.

The MRIcroGL version is 1.2.20211006 GTK2 x86-64 LLVM.

It says "Unable to find Python library". If I press OK, there's another message that shows up on the GUI saying "Unable to start PythonBridge".

I've attached a screenshot of the error. Could you please help with this?

Thank you!

Hello,
 I only have computers with Ubuntu 20.04 and 22.04. In general, Debian distributions like Ubuntu get frozen at the date of their release, so it can be hard to support modern Python on older releases.

One option would be to try:

apt install libpython3-dev

You could also try the Linux version from 7-October-2021 that includes Python
  https://github.com/rordenlab/MRIcroGL/re...

Tell me if either of these work.

Perhaps other users have experience with these older distributions.

Thanks for your reply Chris. Unfortunately neither solution worked.

My Python is up to date. I ran sudo apt install libpython3-dev and got:
libpython3-dev is already the newest version (3.6.7-1~18.04).

I also downloaded the 7-October-2021 version that includes Python, but the GUI wouldn't launch.

I suppose the simplest solution might be for me to update my Ubuntu to a newer version.

Hello
Can you try teh MRIcroGL_linux1804.zip release from here:
  https://github.com/rordenlab/MRIcroGL/releases/tag/v1.2.20220720
the scripting appears to work on Ubuntu 18.04
  https://github.com/rordenlab/MRIcroGL/issues/43
if this works for you, I will upload the files from Github to NITRC for a general release.

Hi Chris, the MRIcroGL_linux1804.zip scripting works on my Ubuntu 18.04.

Thanks so much for your help and for your continuous development of MRIcroGL!
