When I initialize pyimagej with a specific version (let’s say ‘2.1.0’) a Java error comes out:
>>> import imagej
>>> ij = imagej.init('2.1.0')
Then this error shows up:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/altair/anaconda3/envs/py37/lib/python3.7/site-packages/imagej/__init__.py", line 214, in init

return tp._cast(v)
TypeError: Unable to cast 'type' to java type 'java.lang.Class'
Instead, when I initialize without specifying the version some warnings appear, mainly log4j, and an ERROR: cannot create pluguin.
log4j:WARN No appenders could be found for logger (org.bushe.swing.event.EventService).
log4j:WARN Please initialize the log4j system properly.

What are theses errors referencing to? Should I install/fix some package?
Thanks
