I am working on tensorflow 0.12 and am having problem with casting. The following snippet of code does a strange thing:
sess = tf.InteractiveSession()
a = tf.constant(1)
b = tf.cast(a, tf.float32)
print b.eval()
I get a value: 6.86574233e-36
I also tried using tf.to_float()
and tf.saturate_cast
. Both gave the same result.
Please help.
sess = tf.InteractiveSession()
a = tf.constant(1, tf.int64) <--------
b = tf.cast(a, tf.float32)
print b.eval() # 1.0
You need to declare the dtype
for your tf.constant
: https://www.tensorflow.org/api_docs/python/tf/constant
I checked the code in python3 and python2 for the same tensorflow version as well the code seems to be working correctly as in both the cases I got the following output for python2
print b.eval()
1.0
I would suggest checking the tensorflow installation or the virtualenv.
No error in your program.
import tensorflow as tf
sess = tf.InteractiveSession()
a = tf.constant(1)
b = tf.cast(a, tf.float32)
print b.eval()
This is an online environment for TF https://codeenv.com/env/run/gXGpnR/
Test your code there to run, use
由于我发现这仍然受到一些关注,我应该提到较新版本的tensorflow没有显示这种行为,我建议使用tensorflow版本1.13或更高版本
