tf-slim (tensorflow slim) code modification for printing training-accuracy-info to a file

I am looking for a TensorFlow expert to modify the tf-slim code. Specifically, I need to modify the code to print the " training accuracy value" to a file.

https://github.com/tensorflow/models/blob/master/research/slim/eval_image_classifier.py

Currently, the accuracy information is printed to the console. Instead, I want to save that information in a text file.

Code:
# Print the summaries to screen.
for name, value in names_to_values.items():
summary_name = 'eval/%s' % name
op = tf.summary.scalar(summary_name, value, collections=[])
op = tf.Print(op, [value], summary_name)
tf.add_to_collection(tf.GraphKeys.SUMMARIES, op)

Console output:
eval/Recall_5[1]
eval/Accuracy[0.9775]



Skills and Experience:
- Strong proficiency in TensorFlow and tf-slim
- Experience with modifying code in TensorFlow
- Familiarity with logging accuracy metrics such as precision and recall

Deadline:
- The project needs to be completed within one week.
