xlim none

fig = plt.figure()
plt.xlabel('Epoch')
plt.ylabel("Accuaracy")
plt.plot([0.1111, 0.21111], label='train', color='r', linestyle='-', alpha=0.5)
plt.plot([0.1111, 0.21111], label='valid', color='b', linestyle='-', alpha=0.5)
plt.legend(loc="upper right")
plt.xlim(1, 2)
plt.ylim(0, 1)
fig.savefig('Accuaracy_fine-tune_resnet.jpg')

But the output is empty:

if I delete, it is ok :

plt.xlim(1, 2)
plt.ylim(0, 1)

version 3.0.2

You don’t have any data between x =1 and 2.

You are doing a line plot with a single data point and no markers. That's why you aren't seeing anything.

Notice the difference between

• plt.plot(x,y), which would plot a single point at coordinates (x,y)
• plt.plot([y1,y2]), which would plot a line between the two points (0, y1) and (1,y2). In order for this line to be seen the x limits need to (partially) include the range [0,1], and the y limits need to include [y1,y2].

So use plt.xlim(-1,2); plt.ylim(0,1) to see the line. Then change those to your liking.
