My python3 code for plotting is shown below but in my directory there is no output being saved although terminal says **(âSaving frameâ, âimage.0000.pngâ)**

**(âSaving frameâ, âbalongphi.0000.pngâ)** at the end of terminal output.

What changes should i do so that it can work in python3.

```
# Make, name and save plot
fname = 'image.%04d.png' % t
print(('Saving frame', fname))
plt.savefig(dir + fname,bbox_inches='tight')
# plt.show()
# Define next plot(s),
fig = plt.figure(figsize=(20, 7))
# ax = plt.subplot(111)
# Plot B_p or B_phi at chosen R, Theta in Phi direction
bporbphi=0#0 for Bp, 1 for B_phi
plt.clf()
x1 = [i for i in range (0,nphi)]
plt.xticks(size=45)#it is fontsize
plt.yticks(size=45)
plt.tick_params(width=2, which='both', size=15)
plt.tick_params(width=4, which='major', size=22)
plt.minorticks_on()
plt.xlabel(r"$i(\varphi)$", size=60)
if bporbphi == 0:
plt.ylabel(r"B", size=60)
else:
plt.ylabel(r"B$_\varphi$", size=60)
if bporbphi == 0:
plt.plot(x1, B_p[:,jrms,irms], color='black', ls='dashdot',label=r"B$_{p}$",linewidth=6)
plt.plot(x1, br[:,jrms,irms], color='r', ls='solid',label=r"B$_{r}$",linewidth=2)
plt.plot(x1, btheta[:,jrms,irms], color='r', ls='dashed',label=r"B$_{\theta}$",linewidth=3)
plt.plot(x1, bphi[:,jrms,irms], color='r', ls='dotted',label=r"B$_{\varphi}$",linewidth=3)
# Plot a horizontal black line at y=0
x1 = np.linspace(0,70)
y1 = np.zeros(len(x1))
plt.plot(x1, y1, color='black', linewidth=1.5)
plt.legend(loc='best', fontsize='30',ncol=1)
# Make, name and save plot
fname = 'balongphi.%04d.png' % t
print(('Saving frame',fname))
plt.savefig(dir + fname,bbox_inches='tight')
# plt.show()
```

I am getting following warnings while plotiing

/home/raman/Pictures/MikiFor2to3/m2c_read_athdata.py:306: DeprecationWarning: `interp2d` is deprecated in SciPy 1.10 and will be removed in SciPy 1.14.0.
For legacy code, nearly bug-for-bug compatible replacements are
`RectBivariateSpline` on regular grids, and `bisplrep`/`bisplev` for
scattered 2D data.
In new code, for regular grids use `RegularGridInterpolator` instead.
For scattered data, prefer `LinearNDInterpolator` or
`CloughTocher2DInterpolator`.
