gxpy -gxdb.create_line_name

TimNixon

Hi All

I have been using a script that imports LiDAR data to a gdb. It has stopped working recently due to a line that creates the line name to write, as follows:

with gxdb.Geosoft_gdb.open(saveFileName) as gdb:
line_name = gxdb.create_line_name(lineName, gxdb.LINE_TYPE_RANDOM, 0)
gdb.write_line(line_name, xyz, channel_names)

lineName is generated from the LiDAR .asc file name as a string (with extension removed).

The problem is that line_name ends up being an empty string and the write_line fails.

No matter what i put in the args for gxdb.create_line, the line_name is always blank.

Any clue why??

Many thanks.

'D1' is a perfectly valid line name. This is basic stuff, so something mysterious is going on.

9.5 was released just last week, but I doubt it is related to the version number. Perhaps installing to make sure all versions are synchronized will fix it.

Sorry about the challenge here...

@TimNixon I have tried everything I can to get a blank return, but I always get something back. Perhaps put some prints to give me an idea of the what the lineName looks like?
print(lineName) line_name = gxdb.create_line_name(lineName, gxdb.LINE_TYPE_RANDOM, 0) print(line_name)

Hi Ian, thanks for looking at this.

print(lineName) returns '1_1' (I am trying short file names to test)

print(line_name) returns '' (ie. empty string, visible in Spyder's variable explorer).

Tim, sorry works here with 9.5 as "D1_1" is returned. I suspect something else is messed up with your installation, or we are both missing something obvious here.

I suggest you change the line to: line_name = 'D' + lineName

This will move you past this failure and on to the next and maybe that will give us another clue.

Are you using 9.4 or 9.5?

Ian, still getting an error.

GdbException: Invalid line name 'D1'. Use create_line_name() to create a valid name.

I will try to update gxpy and see if that makes a difference.
