Maya的Render.exe：预渲染和后渲染标志生成错误

Question

我正在生成.bat和.sh脚本以启动Maya对许多场景的批渲染（我使用AMD FireRender作为渲染器）

cmds.append('''"{tool}" -log "{log_path}" -proj "{project}" -r FireRender -devc "{render_device}" -rd "{result_dir}" -im "{img_name}" -preRender "python(\\"import base_functions\\"); python(\\"base_functions.main({case_num})\\");" -postRender "python(\\"base_functions.post_render({case_num})\\");" "{scene}"'''.format(
            tool=args.tool,
            log_path=os.path.join(work_dir, LOGS_DIR, case['case'] + '.log'),
            project=projPath,
            result_dir=os.path.join(work_dir, 'Color'),
            img_name=case['case'],
            render_device=args.render_device,
            case_num=case_num,
            scene=case['scene']
        ));

cmds是一个包含命令的列表，稍后将写入脚本。
base_functions是一个python脚本，用于记录和执行每种情况的mel命令

例如，如果我有两个default.ma场景的案例，则生成的script.bat将是：

"C:\Program Files\Autodesk\Maya2020\bin\Render.exe" -log "F:/Workspace/Work/jobs_test_maya/Work/Results/Maya/Smoke\render_tool_logs\MAYA_SM_001.log" -proj "C:/TestResources/MayaAssets\Smoke\default" -r FireRender -devc "gpu" -rd "F:/Workspace/Work/jobs_test_maya/Work/Results/Maya/Smoke\Color" -im "MAYA_SM_001" -preRender "python(\"import base_functions\"); python(\"base_functions.main(0)\");" -postRender "python(\"base_functions.post_render(0)\");" "default.ma"
"C:\Program Files\Autodesk\Maya2020\bin\Render.exe" -log "F:/Workspace/Work/jobs_test_maya/Work/Results/Maya/Smoke\render_tool_logs\MAYA_SM_002.log" -proj "C:/TestResources/MayaAssets\Smoke\default" -r FireRender -devc "gpu" -rd "F:/Workspace/Work/jobs_test_maya/Work/Results/Maya/Smoke\Color" -im "MAYA_SM_002" -preRender "python(\"import base_functions\"); python(\"base_functions.main(1)\");" -postRender "python(\"base_functions.post_render(1)\");" "default.ma"

执行此脚本时，会渲染图像，但在每个日志中都有两个错误：

Error: line 0: setAttr: Too much data was provided. The last 5 elements were not used.

Error: line 0: setAttr: Too much data was provided. The last 2 elements were not used.

它们出现的原因分别是-preRender和-postRender标志。
我可以忽略这些错误，但我需要得到与参考图像完全相似的图像，这还不起作用，这个错误困扰着我。 也许我用错了这些旗子
