tf.raw_ops.InitializeTableFromTextFileV2
Initializes a table from a text file.
tf.raw_ops.InitializeTableFromTextFileV2(
table_handle,
filename,
key_index,
value_index,
vocab_size=-1,
delimiter='\t',
offset=0,
name=None
)
It inserts one key-value pair into the table for each line of the file.
The key and value is extracted from the whole line content, elements from the
split line based on delimiter
or the line number (starting from zero).
Where to extract the key and value from a line is specified by key_index
and
value_index
.
- A value of -1 means use the line number(starting from zero), expects
int64
.
- A value of -2 means use the whole line content, expects
string
.
- A value >= 0 means use the index (starting at zero) of the split line based
on
delimiter
.
