draw roc curve using python sklearn, Matplotlib

import matplotlib.pyplot as plt

from sklearn.metrics import roc_auc_score, average_precision_score

from sklearn import metrics

gt = [1, 0, 1, 0, 1, 1] #origin

pre = [0.9, 0.5, 0.8, 0.4, 0.5, 0.8] #predict

fpr, tpr, thresholds = metrics.roc_curve(gt, pre)

roc_auc = metrics.auc(fpr, tpr)

fig, ax = plt.subplots(figsize=(10,7))

ax.plot(fpr, tpr, label='ROC curve (area = %0.2f)' % roc_auc)

ax.plot(np.linspace(0, 1, 100),

np.linspace(0, 1, 100),

label='baseline',

linestyle='--')

print gpu memory status in python

*install pynvml

https://pypi.org/project/pynvml/

pip install pynvml

*use below code in python code

from pynvml import *
nvmlInit()
h = nvmlDeviceGetHandleByIndex(0)
info = nvmlDeviceGetMemoryInfo(h)
print(f'total    : {info.total}')
print(f'free     : {info.free}')

remove duplicated tuple item in list (python code)

 

print(tuple_list)

tuple_list = [ tuple(sorted(tuple_list[i])) for i in range(len(tuple_list))]

tuple_list = list(set(tuple_list))

print(tuple_list)

before:

[(0, 0), (0, 1), (0, 3), (1, 0), (1, 1), (1, 2), (2, 1), (2, 2), (2, 3), (3, 0), (3, 2), (3, 3)]

After:
[(0, 1), (1, 2), (0, 0), (3, 3), (2, 3), (2, 2), (0, 3), (1, 1)]
