I forget, have you gotten Python working on your computer yet?
I've always been able to run Python on other applications, but I still can't run Python scripts in Golly. This is why I've asked about the existence of lifelib versions of various programs, such as synthesise-patt.
It's really unlikely that very many Python scripts are ever going to get rewritten to work via lifelib instead of Golly, when they work so well (for almost everyone) in Golly. It definitely seems worth finding and fixing whatever the problem is on your system, so that you'll be in the Python Just Works category also.

Again, I don't remember -- did you ever start a thread and provide OS, Golly version, and Python executable name, and the exact symptoms that you get when you try to run a Python script? I just tried searching for a detailed description of your problem along those lines, but didn't come up with anything. Usually if we can just get people to answer questions specifically enough, the conversation ends up going something like this -- i.e., ending with "It worked".

(But I seem to recall you may have been the exception that proves the rule. Mac OS, was it? Maybe Andrew Trevorrow would have some ideas.)

I know that I posted about it in the tools channel, and I think that I included a screenshot.

I was able to find

"I'm going to try to figure out how to make Golly run Python scripts when I have more time over the summer."

from back in April. Is it summertime yet? I also found some path references like "Library/Frameworks/SAVI-pyexec.framework/Versions/Current", but no screenshots offhand. I don't have a Mac, so a screenshot probably wouldn't help me anyway -- but I'll check with Andrew for general troubleshooting advice. I don't even know what the Python dynamic link libraries are called on a Mac... {something}.so or {something}.dylib?

(And then I'll move this discussion out of here to a Mac Python Golly troubleshooting guide thread. Apologies everyone for the wild tangent.)

Okay. What specific flavor of Mac are you running on, what OS version?

And what version of Golly -- 4.0?

My operating system is currently macOS BIg Sur 11.3.1, but I'm pretty sure that I've updated it at least twice since the problem started.
I got the following image when I clicked About Golly.

That seems to me like an odd and ugly place to be looking for About.htm. It belongs in the Help folder directly under Golly's root directory.

I know absolutely zero about this except for what I just Googled, but if you have "AppTranslocation" in the path you might be running into some of the problems described here (?) I could certainly imagine that running Golly from a different randomly chosen path on every run could cause some confusion.

But I'll wait and hope other Mac users can chime in with actual relevant advice.

Also, just to be clear: were you able to check the Library/Frameworks/Python.framework/Versions/3.9/lib/ folder and confirm that there actually is a file called libpython3.9.dylib residing there? The goal is to figure out where on your computer Python 3.9 is installed (and not to try to move or copy any .dylib files from point A to point B at random, to try to make things work) (... I mention this just because on Windows, for some reason, people seem to really enjoy making a thorough mess of their systems by trying this kind of thing.)

Yes. I even had a friend confirm it.

The Library path needs to start with "/", so try entering this :

Code: Select all

/Library/Frameworks/Python.framework/Versions/3.9/lib/libpython3.9.dylib
If that fails try this:

Code: Select all

/Library/Frameworks/Python.framework/Versions/3.9/Python
If both fail then please let me know the output from these Terminal commands:

Code: Select all

file /Library/Frameworks/Python.framework/Versions/3.9/Python
file /Library/Frameworks/Python.framework/Versions/3.9/lib/libpython3.9.dylib
The error from About Golly clearly indicates that Golly.app is being translocated. I'm not sure why that is happening -- maybe Apple have (yet again) changed the security protocols in Big Sur. When you downloaded Golly's .dmg file you should have got a folder called golly-4.0-mac. Where is that folder on your system? In /Applications or ~/Downloads or where?

Quit Golly if it's running, then cd to the golly-4.0-mac directory and run this command:

Code: Select all

xattr -d com.apple.quarantine Golly.app
Now start up Golly and see if About Golly works.

I didn't get a window telling me that Golly couldn't load the Python directory, which I think is progress, but it seems that there is a problem with the Python script. Maybe the copy of the script that I have is meant for the wrong version of Python?

I had some issues with filepaths in Golly before, so I deleted then redownloaded Golly, and just to be safe, I kept Golly in the golly-4.0.1-mac folder (which is in my Downloads folder), instead putting an alias of Golly in my applications folder.

Yes, that seems to have worked.

My guess is that the "w" in the `open` command should be a "wb" to accept `bytes`-like sequences.
Each day is a hidden opportunity, a frozen waterfall that's waiting to be realised, and one that I'll probably be ignoring

I changed that (and made similar changes to lines 30, 32, and 33), and now Golly is doing weird things, like telling me that saving now will not save the changes that I made to earlier generations even though I'm at generation zero.

I think this thread has diverged into a different topic, but did you use `g.new()` or `g.reset()` by any chance?

The script uses g.new().

Definitely stop trying to fix that version of the script. The "bytes" vs. "str" is indeed a marker for Python 2 vs. Python 3 incompatibility.

So instead, post a link to the specific script that you're using, and then we can tell you where the Python 3 version of that script can be found.

Meanwhile, can you confirm that you can now run all the Python scripts that come with Golly 4.0 without any problems?

I can't remember what link I used. Can you just give me a link to the Python 3 version?

Ah, sorry, I hadn't noticed that the error message gave a clue about what script you were running. Here's the Python3 version of synthesise-patt.py.

I seems to partially work. I tested it on the region in these syntheses (3bo$2bobo2$o5bo$2obob2o), and I got this:

Some but not all of the collisions make that region. Do you know why?

Yup, this is a known shortcoming of synthesise-patt.py. It uses a population sequence as the hash values for recognizing active reactions. When there are only a few ticks before an active reaction stabilizes, and when the population just stays steady at 8 ticks or whatever, you can very often get false positives like the ones you're seeing here.

The fix for this is to re-run all the hash sequences to use something more reliable, like octohashes. It's on my to-do list, but it takes several days of processing time so I'm really hoping someone else will get around to it first.

Could you use future discussion to the Scripts subforum, as it seems to be a better place for finding the topic of the discussion?

As for your question, that seems to be a Python 2/3 incompatibility.
For a quick fix, run `2to3 -w .` (or `/Your/Path/To/Python/Tools/Scripts/2to3.py -w .` if that fails)

The quick fix is not terribly reliable for most of these Golly Python scripts, though it does work sometimes. In particular, it works to convert the Python 2 'xrange' syntax that the above error message is complaining about, to Python 3 'range' syntax. Whenever you see a "byte not str" or an 'xrange' error message, you know you've gotten hold of the Python 2 version of something.

Here's the Python 3 version of synthesise-constellation.py.

"byte not str" type issues are usually just a matter of adding a ".decode()" suffix to various ".read()" lines (for example when decoding compressed archives). This kind of thing, for various horrible technical reasons having to do with default ASCII code pages vs. Unicode, can't be handled automatically by the 2to3 script.

Also, I just encountered a difficulty with synthesize-patt. I copied and pasted generation 247 (I typically advance the patterns for a while before running synthesize-patt if the activity lasts long enough in order to get synthesizes that make the desired object as well as sparks or smoke.) of the following pattern into Golly and ran synthesize-patt.py:

Code: Select all

x = 16, y = 15, rule = B3/S23
2bo$obo$b2o2$9bo$9bobo$9b2o6$14bo$13b2o$13bobo!
However, I got the message "0 collisions found". (I did it again just to be sure that I had copied the pattern correctly, and I got the message "0 collisions found" again.)

That's not really a difficulty, it's just another thing to know about synthesise-patt.py. The "colseqs.txt" lookup table has population data for the first 256 ticks of each collision, and it does a comparison with 80 ticks of evolution. So you won't be able to find matches past T=166, unless you reduce the

Code: Select all

GEN_CHECK = 80
at the top of the script. (But if you reduce it too much you'll end up with more false positives.)

Just fair warning, though it's probably obvious: you can't just increase MAX_GENS above 256 the way you can decrease GEN_CHECK, because the colseqs.txt file is pre-computed for 256 ticks. You'd have to regenerate that entire file, which might be a few days of CPU time. If you do that, I'd advise using octohashes instead of population, since that pretty much means you'd be able to search for a single hash value instead of a sequence of N hash values. probably without seeing any false positives at all.

None of these search/match scripts are particularly long or complicated. When you run into problems with one, it's generally worth taking a moment to read through the code and see what it does. Often that can answer this kind of question right away.

Yes, it works when I don't advance so much. Thank you.
