could not convert string to float: '\x1a'

This error occurs when you try to convert a string that contains a non-numeric value (in this case, the character '\x1a') to a float.

To fix this error, you can check the string to ensure it only contains numeric characters before converting it to a float. You can also try to remove any non-numeric characters from the string before converting it.

Alternatively, if you are reading data from a file, make sure that the file is formatted correctly and that there are no unexpected characters in the data.
