pygmt does not run due to error loading library

[thovdl]

Description of the problem

pygmt does not run due to error loading the library gmt_w64.dll.
There is no file gmt_w64.dll.
I have tried making Python refer to gmt.dll, which is available, but this was unsuccessful.

Full code that generated the error

import pygmt

How did you install GMT on Windows? Did you use the Windows installer (i.e. gmt-6.0.0rc5-w64.exe)?

You should find a GMT library file in GMT's bin directory. What's the name of the GMT library? gmt.dll, gmt_w64.dll or any others?

Did you set the environmental variable GMT_LIBRARY_PATH to your GMT library, e.g. C:/programs/gmt6/bin or C:/programs/gmt6/lib?

[thovdl]

I used "conda create --name pyGMT python=3.7 pip numpy pandas xarray packaging gmt=6.0.0rc*"

In my bin directory there was a gmt.dll, none others

I could not find how to change the GMT_LIBRARY_PATH.

[seisman]

I used "conda create --name pyGMT python=3.7 pip numpy pandas xarray packaging gmt=6.0.0rc*"

Did you follow the install instruction? I expect to see gmt in your output of conda list.

In my bin directory there was a gmt.dll, none others

What's the bin path of your GMT's bin directory? Is it C:\programs\gmt6\bin?

[thovdl]

I did follow the install instruction

Conda installed GMT with the packages in C:\Users\myname\AppData\Local\Continuum\miniconda3\pkgs\GMT

Hi @thovdl we've actually been struggling with Windows and never got around to fixing #313. We should have a new release in the next couple of days and will try to revisit that. Right now, PyGMT really doesn't work on Windows. Sorry for the inconvenience.

[weiji14]

Closed with #434, until we release pygmt v0.1.1 or v0.2.0, please follow workaround at #431 to set GMT_LIBRARY_PATH and GMT_SHAREDIR.

Some body please help me using pygmt, projecting hypocenter to A-A1 line and to plot the cross-section along A-A1.
The following is my pygmt script and the resulting figure.
Thank...
import pygmt
import pandas as pd
data=pd.read_csv("G:/LAT_JUPYTER/PyGMT/sumatra_eq.csv")
fig = pygmt.Figure()
fig.basemap(region=[94, 108, -7, 7], projection="M8i", frame="a2g")
fig.coast(shorelines="1.5p,black")

fig.plot(
x=data.longitude,
y=data.latitude,
size=0.15*data.magnitude,
style="cc",
color="red",
pen="black")

fig.plot(x=[96,103],y=[-3,2],pen="2p,black")
fig.text(text="A", x=95.5, y=-3, font="24p,Helvetica-Bold,black")
fig.text(text="A1", x=103.2, y=2.5, font="24p,Helvetica-Bold,black")

pygmt.project(output="cross.dat",
x=data.longitude,
y=data.latitude,
z=data.depth,
center=["-C96/-3"],
endpoint=["-E103/2"],
width="-W-100/100")

fig.show()
fig.savefig("G:/LAT_JUPYTER/PyGMT/sumatra.pdf")

👋🏽 Hi @agusms please post questions on the GMT forum instead: https://forum.generic-mapping-tools.org/

Thanks Dr. Leo..

When I try to import pygmt using pycharm, there are the above problems. But using CONDA runs smoothly.
