Import packing text file into yade

Also, I used O.bodies.append(ymport.text('final.txt',format='x_y_z_r'))
and I got this error:
TypeError: textExt() got multiple values for keyword argument 'format'

Regarding #1, where did you see ymport.text should/ could be used with a format argument ?
Not at https://yade-dem.org/doc/yade.ymport.html#yade.ymport.text, I presume.

For the initial question, I could not reproduce your issue:

from yade import ymport,export
O.bodies.append(sphere((0,0,0),1))
export.text('final.txt', mask=-1)
ymport.text('final.txt', shift=Vector3(0, 0, 0), scale=1.0)

works for me with yadedaily 20220419-6447~fd04d86~focal1. You may try to precise your YADE version and shorten your script for additional support

Dear Jérôme,

Regarding #2 I tried to use [3] which was not correct.

Thank you for your reply.

Dear Jan,

Thank you very much for your kind reply and valuable information.

It was very helpful. I am using Yade 2020.01a.

Also yade I am using, export.text saves files with tabs.

I tried to use the text file without any modification and it works.

I do not know if I can continue my issue here or not.

Because when I ran the code I faced with this error:

TCP python prompt on localhost:9000, auth cookie `sauyce'

Many thanks in advance.

because it has no relation to the OP, it would be better to create a new question ([1], point 5)

Dear Jan,

Thank you very much for your kind reply.

Your valuable recommendations solved my first question.

Sure, I will open a new question for that.

Cheers,
Soheil

Thanks Jan Stránský, that solved my question.

Same issue here and I can't find any methods.
