Failed to create a JVM with the requested environment.

[JeBiUKD]

Dear all,

I have been working successfully with the package before but face problems when setting up PyImageJ on a different computer.

The problem already occurs in the initialization.

Here is a minimal script:

import imagej
ij = imagej.init(mode='interactive')

Error message:

JVMNotFoundException Traceback (most recent call last)
Cell In[1], line 4
2 import imagej
3 # os.environ["JAVA_HOME"] ="C:/ProgramData/Miniconda3/envs/kymo/Library/jre/bin/server"
----> 4 ij = imagej.init(mode='interactive')

File C:\ProgramData\Miniconda3\envs\kymo\lib\site-packages\imagej_init_.py:1200, in init(ij_dir_or_version_or_endpoint, mode, add_legacy, headless)

1199 if not sj.jvm_started():
-> 1200 success = _create_jvm(ij_dir_or_version_or_endpoint, mode, add_legacy)
1201 if not success:
1202 raise RuntimeError("Failed to create a JVM with the requested environment.")

File C:\ProgramData\Miniconda3\envs\kymo\lib\site-packages\imagej_init_.py:1318, in _create_jvm(ij_dir_or_version_or_endpoint, mode, add_legacy)
1316 sj.config.add_option("-Djava.awt.headless=true")
1317 try:
-> 1318 if hasattr(sj, "jvm_version") and sj.jvm_version()[0] >= 9:
1319 # Disable illegal reflection access warnings.
1320 sj.config.add_option("--add-opens=java.base/java.lang=ALL-UNNAMED")
1321 sj.config.add_option("--add-opens=java.base/java.util=ALL-UNNAMED")

File C:\ProgramData\Miniconda3\envs\kymo\lib\site-packages\scyjava_java.py:121, in jvm_version()
116 return jvm_version
118 # JPype was clueless, which means the JVM has probably not started yet.
119 # Let's look for a java executable, and ask via 'java -version'.
--> 121 default_jvm_path = jpype.getDefaultJVMPath()
122 if not default_jvm_path:
123 raise RuntimeError("Cannot glean the default JVM path")

File C:\ProgramData\Miniconda3\envs\kymo\lib\site-packages\jpype_jvmfinder.py:74, in getDefaultJVMPath()
72 else:
73 finder = LinuxJVMFinder()
---> 74 return finder.get_jvm_path()

File C:\ProgramData\Miniconda3\envs\kymo\lib\site-packages\jpype_jvmfinder.py:212, in JVMFinder.get_jvm_path(self)
210 if jvm_notsupport_ext is not None:
211 raise jvm_notsupport_ext
--> 212 raise JVMNotFoundException("No JVM shared library file ({0}) "
213 "found. Try setting up the JAVA_HOME "
214 "environment variable properly."
215 .format(self._libfile))

JVMNotFoundException: No JVM shared library file (jvm.dll) found. Try setting up the JAVA_HOME environment variable properly.

I then tried to set the JAVA_HOME environment:

import imagej
import os
import imagej.doctor
imagej.doctor.debug_to_stderr()

os.environ["JAVA_HOME"] ="C:\Program Files\AdoptOpenJDK\jre-8.0.242.08-hotspot"
# ij = imagej.init('2.9.0')
ij = imagej.init(mode='interactive')

Then I get the following error message:

[NicoKiaru]

Is it still failing today? Maybe you tried unluckily during a maven.scijava.org server downtime?

[JeBiUKD]

No unfortunately it still does not work.

[ctrueden]

@JeBiUKD I think the JAVA_HOME needs to be set further up the directory chain. Try:

os.environ["JAVA_HOME"] ="C:/ProgramData/Miniconda3/envs/kymo/Library"

and

os.environ["JAVA_HOME"] ="C:/ProgramData/Miniconda3/envs/kymo/Library/jre"

If neither of those works, try also with backslashes \ instead of forward slashes /?

@hinerm Do you have experience with setting the JAVA_HOME variable on Windows from Python? Does it work? How should it be?

[JeBiUKD]

Thank you for the suggestions. I have tried this already and I think the JAVA_HOME set up actually worked.

I have the feeling that the download from maven seems to fail. I checked the folder structure between the two computer and noticed that my .jgo folder looks different. I transferred all the files from the computer where imagJ init did not cause a problem and now it seems to work. :)

Do you have an idea of what was the difference ?

[JeBiUKD]

I am not sure how the .jgo folders looked before initializing ImageJ the first time on the other computer, but for the folders on my PC which had trouble initializing imagej in python was missing almost all .jar files. I transferred the missing .jar files and then it worked. Now when running the initialization I get the note that JVM is already running (similar to the other computer).
