In the debugger, stumbled tf.decode_csv tensorflow of () the accuracy of the csv file parsing problem, there is a csv file data, raw data 39.9828850668, but the call tf.decode_csv () parses, print out the value of 39.98288345. If the original data is modified data 40.1234, after parsing it is 40.12340164. The reason should be float64 precision float or too high bar. I hope someone can explain why.
