recently I'm running a deep learning model using tensorflow 1 and python 3 and I met this bug.
I have some code like this:
_, run_lr, loss = sess.run([optimizer, run_lr_op, loss_op], feed_dict=dict(zip(placeholders, train)))
eval_input = sess.run(eval_input_op, feed_dict=dict(zip(placeholders, train)))
batch_eval_inputs.append(eval_input)
if step % 10 == 0:
print('\nstep {}: train loss {:.4f} run_lr {:.6f}'.format(step, loss, run_lr))
and the print() function doesn't output anything.
I also tried adding some other simple print(), like add a print('hello world') before if. But this doesn't output anything either.
