mathplotlib savefig FileNotFoundError

[drinkOut]

Hi!

I've made a figure using matplotlib and now I'm trying to save it to file using matplotlib.pyplot.savefig

import matplotlib.pyplot as plt

# . . .

plt.savefig("result.png")

Unfortunately it occurs FileNotFoundError at plt.savefig call.

Does anybody know, how can this problem be solved?

Unfortunately it occurs FileNotFoundError at plt.savefig call.

Please post full traceback you get in error tags. Also it would be nice to post full code (minimal verifiable example that reproduce the problem).

Jupyter Notebook cell:

import matplotlib
import matplotlib.pyplot as plt
import numpy as np

y = [2,4,6,8,10,12,14,16,18,20]
x = np.arange(10)
fig = plt.figure()
ax = plt.subplot(111)
ax.plot(x, y, label='$y = numbers')
plt.title('Legend inside')
ax.legend()
#plt.show()

fig.savefig('plot.png')

The code work when i test in Jupyter Notebook.
Try this,so for me plot.png get save in C:\\1_notebook.
A folder i have made to keep all notebooks.

import os

os.getcwd()

Output:
'C:\\1_notebook'
