I have a 3 dimensional numpy array
([[[0.30706802]],
[[0.19451728]],
[[0.19380492]],
[[0.23329106]],
[[0.23849282]],
[[0.27154338]],
[[0.2616704 ]], ... ])
with shape (844,1,1) resulting from RNN model.predict()
y_prob = loaded_model.predict(X)
, my problem is how to convert it to a pandas dataframe. I have used Keras
my objective is to have this:
0 0.30706802
7 0.19451728
21 0.19380492
35 0.23329106
42 ...
...
815 ...
822 ...
829 ...
836 ...
843 ...
Name: feature, Length: 78, dtype: float32
idea is to first flatten the nested list to list than convert it in df using from_records
method of pandas dataframe
import numpy as np
import pandas as pd
data = np.array([[[0.30706802]],[[0.19451728]],[[0.19380492]],[[0.23329106]],[[0.23849282]],[[0.27154338]],[[0.2616704 ]]])
import itertools
data = list(itertools.chain(*data))
df = pd.DataFrame.from_records(data)
Without itertools
data = [i for j in data for i in j]
df = pd.DataFrame.from_records(data)
Or you can use flatten()
method as mentioned in one of the answer, but you can directly use it like this
pd.DataFrame(data.flatten(),columns = ['col1'])
Here you go!
import pandas as pd
y = ([[[[11]],[[13]],[[14]],[[15]]]])
a = []
for i in y[0]:
a.append(i[0])
df = pd.DataFrame(a)
print(df)
Output:
0
0 11
1 13
2 14
3 15
Feel free to set your custom index values both for axis=0 and axis=1.
You could try:
s = pd.Series(your_array.flatten(), name='feature')
https://docs.scipy.org/doc/numpy/reference/generated/numpy.ndarray.flatten.html
You can then convert the series to a dataframe using s.to_frame()
