Removing axis labels matplotlib

Question

I have this image and I don't know how to remove the axis labels from the top and right hand side.

I have tried:

ax.spines['right'].set_visible(False)
ax.spines['top'].set_visible(False)

and

ax.yaxis.set_label_position("left")
ax.xaxis.set_label_position("bottom")

and

plt.tick_params(axis='both', left='off', top='off', right='off', bottom='off', labelleft='off', labeltop='off', labelright='off', labelbottom='off')

This is my code for plotting:

 ax = plt.axes(projection=ccrs.PlateCarree())

 plt.pcolormesh(reflon, reflat, par_interp, vmin=0, vmax=2, cmap=plt.cm.jet, 
 transform=ccrs.PlateCarree()) 

 plt.colorbar()

 rowskip = 50
 colskip = 50 
 plt.quiver(reflon[0::rowskip,0::colskip],reflat[0::rowskip,0::colskip],
           u[0::rowskip,0::colskip],v[0::rowskip,0::colskip], 
           color='black',pivot='middle', alpha=0.7, width=0.015, units='inches', 
            transform=ccrs.PlateCarree())

 ax.gridlines(crs=ccrs.PlateCarree(), draw_labels=True,
                     linewidth=0.5, color='gray', alpha=0.5, linestyle='--')

 ax.coastlines()
 figtitle = siteid+': HS (m MSL) and Wnd: '+dstr
 ax.set_title(figtitle)

 dtlabel = datetime.date.strftime(dt,'%Y%m%d%H%M%S')
 dtlabel = dtlabel[0:8]+'_'+dtlabel[8:14]
 filenm = dtlabel+'.png'
 plt.show()
 plt.savefig(filenm,dpi=150,bbox_inches='tight',pad_inches=0.5)

Also, if you know how to make it so the east coast of the US is not red, let me know. Trying to figure that out too. Might be an issue with the data I am plotting though.

Answer 1

Found answer here https://scitools.org.uk/cartopy/docs/v0.13/matplotlib/gridliner.html

   gl.xlabels_top = False
   gl.ylabels_right = False

Answer 2

According to this, you could simply color the labels white by

plt.xticks(color='w') and plt.yticks(color='w')

with plt = matplotlib.pyplot
