一、總結
一句話總結:
metrics:英 /ˈmetrɪks/ :n. 度量;作詩法;韻律學
1、area讀音?
英 /ˈeəriə/
2、Requests is an elegant and simple HTTP library for Python, built for human beings.?
elegant:英 /ˈelɪɡənt/ :adj. 高雅的,優雅的;講究的;簡煉的;簡潔的
3、The Session object allows you to 【persist certain】parameters across requests. It also persists cookies across all requests made from the Session instance, and will use urllib3’s connection pooling. ?
persist:英 /pəˈsɪst/:vt. 堅持說,反復說
certain:英 /ˈsɜːtn/ :adj. 某一;必然的;確信;無疑的;有把握的
Session對象允許您在請求中保留某些參數。 它還會在會話實例發出的所有請求中保留cookie,並將使用urllib3的連接池。
4、python爬蟲庫Requests的response對象的iter_content(chunk_size=1, decode_unicode=False)方法?
chunk:英 /tʃʌŋk/:n. 大塊;矮胖的人或物
Iterates over the response data. When stream=True is set on the request, this avoids reading the content at once into memory for large responses. The chunk size is the number of bytes it should read into memory. This is not necessarily the length of each item returned as decoding can take place.
chunk_size must be of type int or None. A value of None will function differently depending on the value of stream. stream=True will read data as it arrives in whatever size the chunks are received. If stream=False, data is returned as a single chunk.
If decode_unicode is True, content will be decoded using the best available encoding based on the response.
5、sample讀音?
sample:英 /ˈsɑːmpl/ :n. 樣品,樣本;
6、exit讀音?
exit:英 /ˈeksɪt; ˈeɡzɪt/ :n. 出口,通道;退場
7、SymPy有三個內建的數值類型:實數,有理數和整數。有理數類用兩個整數來表示一個有理數。分子與分母,所以Rational(1,2)代表1/2,Rational(5,2)代表5/2,等等。?
rational:英 /ˈræʃnəl/:adj. 合理的;理性的 n. 有理數
8、SymPy中(x/y).subs([(x, 0), (y, 0)], simultaneous=True)?
simultaneous:英 /ˌsɪmlˈteɪniəs/ :adj. 同時的;聯立的;同時發生的
9、比如機器模型每次訓練的【准確度】?
accuracy:英 /ˈækjərəsi/ :n. [數] 精確度,准確性
10、plt.plot(history.epoch,history.history.get('loss'))?
epoch:英 /ˈiːpɒk/:n. [地質] 世;新紀元;新時代
11、matplotlib畫散點圖:plt.scatter(data.Education,data.Income)?
scatter:英 /ˈskætə(r)/ :v. 撒播;散開 n. 零星散布的東西:
12、tensorflow2模型創建:model = tf.keras.Sequential()?
sequential:英 /sɪˈkwenʃl/ :adj. 連續的;相繼的
