Having troubles with import trident

[Majid Uzbak]

Hello
We are trying to work with Trident, but we are getting an error, which wont let us to import trident, in python.

The error says: ModuleNotFoundError: No module named 'yt.convenience'

Anybody have had this kind of error too ? How can we fix it?

Best regards

[Matthew Turk]

Hi Majid,

That is likely related to a different version of yt being installed,
or yt not being installed at all. Can you verify that you are able to
"import yt" by itself?

Hello Matthew

I have tried the yt, with spyder and also jupyter notebook and in both case, it does work.
for example I can load the data and also plot it with yt.ptojectionplot.

I found that the stable version of trident uses yt.loaders instead of yt.convenience.

So I uninstalled that version and installed the development version of the trident, from here using cmd (I am a macOS user):

https://trident.readthedocs.io/en/latest/installation.html

But in this case, with the spyder I can run "import trident" with no error, but when I am trying to make a simple ray using this:

"ray = trident.make_simple_ray(ds, start_position=ray_start, end_position=ray_end, data_filename="ray.h5", lines=line_list, ftype=('gas'))"

I get this error:

"Traceback (most recent call last):
  File "/Users/majiduzbak/.spyder-py3/temp.py", line 23, in <module>
    ray = trident.make_simple_ray(ds,
AttributeError: module 'trident' has no attribute 'make_simple_ray'"

And jupyter notebook does not run it at all.

With regards.

The version of the yt is: 4.1.dev0

I cannot get the vresion of the trident, which can be, because the trident is not installed correctly?

Matt is correct. I have been meaning to put out a new stable version of trident since the new year and haven’t found time. Until I do so, the current fix is to install the development version of yt and trident: https://trident.readthedocs.io/en/latest/installation.html#installing-the-development-version-of-yt-and-trident

Hi Cameron
I am trying to get the development version running, everything runs fine until, I clone the trident and when I enter the command: "pip install -e ."

I get this error: "

error: legacy-install-failure

× Encountered error while trying to install package.

╰─> matplotlib "

I also tried to pip install this package separately, out of luck.

Terrific! I will change things on our end to address this when I’m back.

Hi Cameron.
After I changed to ' matplotlib', it is now working fine. 

Thank you for all your help
