The map made is always blocked by color blocks

Q&A PyGMT Q&A

As shown in the figure below, the resulting figure always has color blocks, and there seems to be no problem with my code. I made it in pycharm, because it seems that the pygmt package always can’t be found in jupyterlab in my computer(macbook)

there is my code:

import pygmt
grid = pygmt.datasets.load_earth_relief(resolution="01m", region=[180, 310, -40, 30])
fig = pygmt.Figure()
fig.coast(
    region=[180, 310, -40, 30],
    projection="M10c",
    land="darkgray",
    water="white",
    borders="1/0.5p",
    shorelines="1/0.5p",
    frame="ag",
)
fig.grdimage(
    grid=grid,
    cmap="etopo1",
    projection="M10c",
    frame=True,
)

fig.colorbar(frame=["a2000", "x+lDepth", "y+lm"])
fig.savefig("fuyu.pdf")

Usually means that those tiles (in ~/.gmt/server/earth/earth_relief/ earth_relief_01m_p or possibly earth_relief_01m_g got corrupted during download or similar so they are junk. Solution is the either remove those specific tiles (they will then be auto-downloaded when you run your script again) or the whole directory if you cannot figure out which ones (e.g, N60W030.earth_relief_01m_p.jp2 is one name with coordinates referring to lower-left corner, for instance).

Please, wrap you code in triple backticks ```

Thank you! I removed the whole directory, then restarted the code and the green blocks disappeared.
