1. ENVI+IDL
1、Invalid object reference: <OBJREF ()>.
restart-idl
2. Arcgis
1、Provide your license server administrator with the following information:Error
2. Import TIFF numerical distortion
The normal value is displayed in ENVI, the maximum and minimum values of imported TIFF data have changed, and the attribute table cannot be opened. When the pixel type of the raster file (such as a tif format file) is a floating point type, the attribute table will become invalid and turn gray.
Solution: Numerical analysis in the Spatial Analyst tool – convert the value to an integer;
after completion, you can export the data from the file-data----and convert it to TIFF
3. The imported map is too flat
Right click - data frame properties -
4. Failed to use the table partition statistics tool
Solution 1: The raster data is non-integer, use the -Convert to Integer- tool to convert the raster data into an integer
Solution 2: The output path is wrong (1. If the output name is too long, it will fail. 2. If there is a "." in the path, it will fail Fail 3. If the first character of the output name is data, an error will be prompted. ------Anyway, I changed the name to full letters later, and the name cannot be too long during Python batch processing, and there will be errors)
3. Python
1. Unable to install package - change python third-party library installation
1.1 The correct version of 'pip' installed by the python interpreter.
(It is said that multiple Python versions are installed, but the main reason may be that the network is not working)
Solution: Change the third-party library installation and download path
Just add the download source
1. Tsinghua source https://pypi.tuna.tsinghua.edu.cn/simple/
4、Archgis&Python
1、Runtime error File “string”
Runtime error
Traceback (most recent call last):
File "", line 15, in
TypeError: 'unicode' object is not callable
Solution: 1. It seems that it is because the folder is newly created and cannot be recognized, just change the output folder
2 , code error
5. R
1. R runs polt()—R Graphics: Device 2 (ACTIVE)
Scenario: When using the geographic detector of the R package, when plotting results (there should be multiple image results), the last image result will overwrite the previous image result. Display graphs in the figure window pane instead of opening new windows in RStudio
Method 1 (failure): Uninstall and update R packages
Method 2 (success): Uninstall and update Rstudio
