Is it possible to save a histogram during evaluation using the estimator API?
I couldn't find a solution since the estimator api does not write down any summaries during evaluation and I can only add scalars to the evaluates metrics.
For the sake of those who came here and haven't found a solution, I will update that I used the above approach, with a slight modification:
summary_writer = tf.compat.v1.summary.FileWriter(
logdir=self.model_dir + '/eval_histograms/',
filename_suffix='.host_call')
summary_ops = [tf.compat.v1.summary.histogram(name=k, values=v)
for k, v in
prepare_endpoints_for_summary(endpoints).items()]
eval_hooks = [
tf.estimator.SummarySaverHook(save_steps=1,
summary_writer=summary_writer,
summary_op=summary_op)
for summary_op in summary_ops]
