Throws error: pyvips.error.Error: unable to call embed linear: vector must have 1 or 3 elements

[caleb87]

Script runs for awhile, then throws the following error.

Running Ubuntu 18.04, gdalinfo is 2.2.3. Any ideas?

ubuntu@:~$ sudo gdal2mbtiles --min-resolution 1 --max-resolution 15 test.tif test.mbtiles

Can you provide the test tif that generated this error?

[caleb87]

The files are available here:

http://54.161.226.75/original.tif
http://54.161.226.75/epsg3857.tif

original.tif (about 15MB) is the image I started with, and epsg3857 which has been converted to EPSG 3857 (about 150MB). Both are throwing the error.

[jordiecometrica]

Alright, let's save the file here: original.tif.txt

Okay, figured it out. Had to change the filename extension so that github would allow it, but it's still very much a tif, not a txt. Just drop the extraneous filename extension the day someone downloads it and wants to try addressing this problem.

I also have this problem.
gdal2mbtiles haifenxian1024.tif haifenxian1024.mbtiles --no-fill-borders --min-resolution 10 --max-resolution 19
This problem occurs when --no-fill-borders and --min-resolution is used.
but it was when no --no-fill-borders ,it was very slowly（It seems that it was the whole earth）

Same problem here with a 30000 pixel tif.
At first I thought it was a problem of gdal 3 that get installed with the instructions, but the problem continues even with installing gdal 2.4.4

[csustjl]

Now I have this problem too, did you solve this problem before? gdal=2.2.2 pyvips=2.1.8 GDal2mbtiles = 2.1.0

I have the same problem, has anyone found a solution?
