You’re encountering exactly the same issue I had! Just yesterday I was working on this part of the data. The problem here lies in how the output file you created is formatted. It seems the system can only read line breaks as /n, but if you use the default setting, it becomes /r/n, which the system fails to read correctly. Therefore, when exporting a CSV file, you need to add this line:
lineterminator="\n"
df.to_csv(f, sep=" ", index=False, header=False, float_format="%.3f", lineterminator="\n")
Or, if you're manually creating new lines in the file, make sure to use \n only—otherwise, the import function won’t be able to read the file properly.

After checking your file (by opening it in Notepad++ and going to View → Show Symbol → Show End of Line), I found that the issue you mentioned is indeed present. Try adjusting it accordingly.
