Mysql(Mariadb) DB 용량 확인, volume check DB 별 용량 확인하는 쿼리 (volume by db name) SELECT table_schema "DB Name", ROUND(SUM(data_length + index_length) / 1024 / 1024, 1) "MB" FROM information_schema.tables GROUP BY table_schema; 만약 전체 용량을 확인하고 싶다면 (Total volume) SELECT SUM(data_length+index_length)/1024/1024 "USED_MB", SUM(data_free)/1024/1024 "FREE_MB" FROM information_schema.tables; 2019. 4. 17.
tensorflow Keras - not_equal, cast Test 기본형태tf.keras.backend.not_equaltf.keras.backend.not_equal(x, y)Returns:A bool tensor.- Element-wise inequality between two tensors.​​tf.keras.backend.casttf.keras.backend.cast(x, dtype)Returns:Keras tensor with dtype `dtype`.- Casts a tensor to a different dtype and returns it.with tf.Session() as sess: test_input1 = Input(shape=(1, )) test_equal = K.not_equal([1, 2, -1, -1, 4, 5], -1) tester = K.. 2019. 3. 13.
keras Masking Test Definition:Masks a sequence by using a mask value to skip timesteps.For each timestep in the input tensor (dimension #1 in the tensor), if all values in the input tensor at that timestep are equal to mask_value, then the timestep will be masked (skipped) in all downstream layers (as long as they support masking).​But, I want to know the real output from Masking that expected.​Below to see how th.. 2019. 3. 13.
the longest palindromic substring Given a string s, find the longest palindromic substring in s. You may assume that the maximum length of s is 1000.Example 1:Input: "babad" Output: "bab" Note: "aba" is also a valid answer. Example 2:Input: "cbbd" Output: "bb"​Palindromic 이라는 것은 회기되는 단어를 이야기 한다. 예를들어 "토마토", "스위스" 와 같은 문장이다. 위 문제에서는 가장 긴 회기단어를 추출하라는 것이다. ​Python Solution:class Solution: def longestPalindrome(self, s: str) -> str:.. 2019. 3. 6.
