xcode 引入scipy，真机调试scipy依赖的文件找不到

[baixiaochunbudanchun]

您好，我在xcode OC语言，集成python环境，然后调用我自己的脚本，我的脚本依赖了scipy使用 from scipy.signal import butter, sosfiltfilt, find_peaks, savgol_filter
from scipy.signal.windows import gaussian 这几个依赖函数，然后报如下错误

❌w模块导入失败，
Numpy 版本: 2.3.5

我是按照项目的使用说明集成的，我该怎么解决这个问题?

[baixiaochunbudanchun]

scipy.linalg/ scipy.signal的 .so扩展（cython_blas, cython_lapack）在 iOS 真机运行时报 symbol not found in flat namespace 'dcabs1'，原因是 BLAS 符号未静态链接进 .so，iOS 的 Accelerate BLAS 符号不公开无法在 flat namespace 解析。作者可以在构建时把 OpenBLAS 或静态 BLAS 的 dcabs1, _lsame_等符号链接进这些 .so，或改用完整静态合并的 scipybundle。

[yu314-coder]

你好，这个问题已经定位并修复，修复已经推送到 main。

原因

scipy.linalg.cython_blas 引用了三个 参考 BLAS 辅助函数：dcabs1、scabs1、lsame。苹果的 Accelerate 框架提供了 BLAS/LAPACK 主体内核（dgemm、zgesv 等），但没有导出 dcabs1 / scabs1；而 cython_blas 是在 flat namespace（平面命名空间） 里查找它们的，所以真机上 dyld 一旦找不到 dcabs1 就崩溃：

symbol not found in flat namespace '_dcabs1_'

（lsame 其实在 Accelerate 里，是 two-level 绑定，没问题；真正缺的只有 dcabs1 / scabs1。）

最简单的解决办法（推荐）

在你自己的 App target 里加入一个很小的 C 文件，把缺失的符号放进主程序，flat-namespace 查找就能解析到——不用改 scipy，也不用额外的 dylib：

// blas_compat_stubs.c
#include <math.h>
double dcabs1_(const double *z) { return fabs(z[0]) + fabs(z[1]); }
float  scabs1_(const float  *c) { return fabsf(c[0]) + fabsf(c[1]); }
int lsame_(const char *ca, const char *cb, long la, long lb) {
    (void)la; (void)lb;
    int a=(unsigned char)ca[0], b=(unsigned char)cb[0];
    if (a>='a'&&a<='z') a-=32; if (b>='a'&&b<='z') b-=32; return a==b;
}

把 blas_compat_stubs.c 加进 Xcode 的 Build Phases → Compile Sources，重新编译，import scipy.signal / scipy.linalg 就能正常加载了。

仓库里已经带上的修复

为了让打包好的 scipy「开箱即用」，main 上现在也加了：

• fortran/blas_compat_stubs.c — 这三个辅助函数的源码；
• Frameworks/scipy_aux/libscipy_blas_stubs.dylib — 预编译好的（arm64-ios，ad-hoc 签名，@rpath）；
• 给 cython_blas*.so 加了 LC_LOAD_DYLIB，运行时解析这个 dylib；
• scripts/appstore/build-blas-stubs.sh — 每次重建 scipy 后可重新生成；
• docs/scipy_ios_dcabs1_fix.md 有详细说明，test_scipy_blas_fix.py 可在真机上验证。

如果你是直接嵌入这个包，记得把 libscipy_blas_stubs.dylib 拷进 App 的 Frameworks/ 并保证有 @rpath 能找到它；或者直接用上面「最简单办法」，连 dylib 都不用。

我在真机（iPad / iOS 26）上验证过：复数 linalg.solve、eigvals，以及 butter→sosfiltfilt→savgol_filter→find_peaks 信号管线都通过了。麻烦你试一下，确认是否解决，谢谢！

English: Accelerate doesn't export the reference-BLAS helpers dcabs1/scabs1, and cython_blas looks them up in the flat namespace → dyld aborts on device. Easiest fix: add the tiny blas_compat_stubs.c above to your app target (Build Phases → Compile Sources) so the symbols live in your main binary — no scipy patching, no extra dylib. main now also bundles libscipy_blas_stubs.dylib + an LC_LOAD_DYLIB on cython_blas*.so so the packaged scipy works out of the box (see docs/scipy_ios_dcabs1_fix.md; verify on-device with test_scipy_blas_fix.py). Please give it a try and let me know if it resolves the crash.

作者你好，非常感谢你给的回复及解决方案，我通过导入libfortran_io_stubs.dylib，libsf_error_state.dylib，libscipy_blas_stubs.dylib三个文件，在真机上能够将脚本模块导入成功，并获取对应的函数。
现在我又遇到提交商店代码审核的问题，按照你的readme文档操作，执行了wrap-loose-dylibs脚本，但是仍然会报Upload-fail-with-errors.txt文档中的错误，
Run-Script-build-phase.txt 是我按照5. Boot Python and add the bundles to sys.path进行的项目配置
Run-Wrap-loose-dylibs.txt是我按照App Store distribution 指导进行的配置，
wrap-loose-dylibs-result.txt 是编译之后脚本执行的结果，
我的项目只引用了numpy和scipy 两个库，请你在帮我看看什么原因导致商店审核不通过

[yu314-coder]

很高兴 dcabs1 的问题已经解决，scipy 在真机上能正常导入了 👍

关于上传 App Store 失败 —— 先说明一下：你附的四个 .txt（Upload-fail-with-errors.txt 等）通过邮件回复发上来时变成了失效链接。GitHub 的邮件回复网关只保留图片附件，会把 .txt 之类的文件丢掉，所以它们点开都是 404（对我、对你都一样）。以后如果要我看日志，麻烦直接把文件拖进网页评论框（不要用邮件回复），链接才有效。

不过你的两张截图已经足够定位问题了：

① General 标签 —— 三个桩 dylib 都设成了 Embed & Sign：
libfortran_io_stubs.dylib、libscipy_blas_stubs.dylib、libsf_error_state.dylib
也就是以松散 dylib（loose .dylib）的形式打进 App 包里。

② Build Phases 的执行顺序：

Compile Sources (24)
Link Binary With Libraries (6)
Copy Bundle Resources (19)
Sign Python Binary Modules
Run Wrap-loose-dylibs        ← 脚本在这里执行
Embed Frameworks (4 items)   ← 但那三个 dylib 是在这之后才被嵌入的

这个顺序就是根因。 Run Wrap-loose-dylibs 排在 Embed Frameworks 前面，所以脚本去扫描 Frameworks/ 时，那三个桩 dylib 还没被拷进去（Embed Frameworks 在后面才拷）。脚本把 python-ios-lib 包自带的二进制都正确打包成 framework 了，唯独漏掉了你手动加的这三个 —— 它们最终以松散、未打包的形式留在了 .app/Frameworks/ 里。Apple 的校验器就会拒绝这些松散 .dylib（ITMS-90xxx 里 "Invalid Bundle / 不支持的动态库" 那一类）。

解决办法（拖一下顺序就行）：
在 CustomCalculator target → Build Phases，把 Run Wrap-loose-dylibs 拖到最底部，放到 Embed Frameworks 的下面，让它在 dylib 被嵌入之后再执行打包。然后重新 Archive → 上传 即可。

README 里写的是"放在最后的隐式 code-sign 之前"，这点没错；这里补一句更关键的：必须排在 Embed Frameworks 之后，否则脚本看不到刚嵌进来的 dylib。

可选精简：把那段很小的 blas_compat_stubs.c 加进 App target（Build Phases → Compile Sources），就能把 libscipy_blas_stubs.dylib 整个去掉（少一个松散 dylib）；但另外两个 libfortran_io_stubs / libsf_error_state 仍然要靠 wrap 脚本打包成 framework —— 所以调整 Build Phase 顺序才是这次的关键。

调整后如果还报错，请把 Upload-fail-with-errors.txt 的内容直接贴在评论里（或拖进评论框），我再帮你看是具体哪一类。

English summary: Your four .txt logs arrived as dead links — GitHub's email-reply gateway only keeps image attachments, so the .txt files were never hosted (they 404 for everyone). Please drag them into a web comment if you want me to read them next time. Your two screenshots are enough, though: the three stub dylibs (libfortran_io_stubs, libscipy_blas_stubs, libsf_error_state) are Embed & Sign (loose dylibs), and in Build Phases your Run Wrap-loose-dylibs phase runs before Embed Frameworks — so those three dylibs aren't in Frameworks/ yet when the wrap script scans, and they ship loose → Apple rejects them (ITMS-90xxx Invalid Bundle / unsupported dylib).

Fix: in the CustomCalculator target → Build Phases, drag Run Wrap-loose-dylibs to the bottom, below Embed Frameworks, then re-Archive and upload. (Optionally add blas_compat_stubs.c to the app target to drop libscipy_blas_stubs.dylib, but the phase reorder is the real fix.) If it still fails, paste the contents of Upload-fail-with-errors.txt directly and I'll pinpoint the exact category.

[baixiaochunbudanchun]

非常感谢你的回复和指导，由于中国访问github不是很稳定，我分几步提交我遇到的问题。第一、我听取你的建议，使用blas_compat_stubs.c 加进 App target（Build Phases → Compile Sources）这种方式，但是报了如下如错误，

因此我还是使用原来的方法，我调整了Build Phases 的执行顺序：

Copy Bundle Resources (19)
Embed Frameworks (4 items)
Sign Python Binary Modules
Run Wrap-loose-dylibs
编译时报了如下图错误

我通过修改 wrap-loose-dylibs 脚本，解决上面问题，进行打包提交，

iOS placeholder for torch_shm_manager

The real torch_shm_manager is a Mach-O executable used by

torch.multiprocessing to spawn shared-memory daemons via fork().

iOS forbids fork() in app bundles AND App Store rejects standalone

Mach-O executables in app_packages/, so we replace the binary with

this text placeholder. PyTorch's manager_path() finds the file,

os.path.exists() returns True, _C._initExtension() succeeds, and

torch loads with most features intact (tensors, autograd, nn,

optim, jit, save/load, ExecuTorch, CoreML — all work).

torch.multiprocessing's fork-based APIs will fail at call time,

which is the actual behavior on iOS regardless.

iOS placeholder for torch_shm_manager

The real torch_shm_manager is a Mach-O executable used by

torch.multiprocessing to spawn shared-memory daemons via fork().

iOS forbids fork() in app bundles AND App Store rejects standalone

Mach-O executables in app_packages/, so we replace the binary with

this text placeholder. PyTorch's manager_path() finds the file,

os.path.exists() returns True, _C._initExtension() succeeds, and

torch loads with most features intact (tensors, autograd, nn,

optim, jit, save/load, ExecuTorch, CoreML — all work).

torch.multiprocessing's fork-based APIs will fail at call time,

which is the actual behavior on iOS regardless.

Thanks for the very detailed write-up and screenshots 🙏 Four points:

1) scipy _dcabs1_ — resolved. Good.

2) blas_compat_stubs.c build failure ("Could not build module 'Foundation'/'UIKit'", "Module 'ObjectiveC.NSObject' requires feature 'objc'"): that's the .c file inheriting your app's Objective-C prefix header — a pure-C translation unit can't build the ObjC system modules. Fix: rename it to blas_compat_stubs.m (Objective-C is a superset of C, so the stubs still compile), or exclude it from the prefix header. I've updated the README example to .m.

3) code = 90171 (loose .so "binary file is not permitted"). Your diagnosis is exactly right — App Store requires every Mach-O to live inside a .framework under Frameworks/. The issue is the SwiftPM resource-bundle layout: the .so in python-stdlib/lib-dynload/ and inside python-ios-lib_*.bundle/ are loose, and the script I'd pointed you at (wrap-loose-dylibs.sh) only covers the app_packages/ layout — that was a documentation mistake on my side.

The repo already ships the script built for exactly this layout:

• scripts/appstore/wrap-binaries-as-frameworks.sh
• scripts/appstore/python_ios_lib_import_hook.py

It wraps every .so in lib-dynload/ and the bundles into Frameworks/*.framework, rewrites the cross-LC_LOAD_DYLIB references, re-signs, and a runtime import hook (MetaPathFinder) re-routes import numpy._core… to the framework — i.e. the same thing your manually-extended script does. I had wrongly marked it "deprecated"; I've corrected the README and added an App Store Connect submission section with the full SwiftPM steps (build phase + import-hook bootstrap):

https://github.com/yu314-coder/python-ios-lib#app-store-connect-submission

4) "Upload Symbols Failed: no dSYM for Python.framework" is a non-blocking warning, not a rejection — the prebuilt Python.framework ships without a dSYM. Untick "Upload your app's symbols" in the Distribute flow, or ignore it.

Thanks again for the thorough repro — it caught a genuinely misleading bit in the docs.

作者你好，再次感谢你的回复及技术指导，我根据你的README.md文档，使用Swift Package Manager这种方式，对项目进行修改，使用blas_compat_stubs.m方式替换libscipy_blas_stubs.dylib文件，同时我还执行了wrap-binaries-as-frameworks.sh脚本，然后项目在debug环境报如下错误。

同时我还尝试使用python_ios_lib_import_hook.py脚本，但是失败，下图是我的使用方式

我还尝试先后同时运行wrap-loose-dylibs.sh 和wrap-binaries-as-frameworks.sh 脚本，打包上传应用上商店，还是被拒

还请你在项目中写一个完整的可以审核通过的 xcode OC demo让我学习，我的项目目前只导入numpy和scipy,
再次感谢你的回复与技术指导

Run Script Wrap-binaries-as-frameworks 下面内容是我执行wrap-binaries-as-frameworks.sh的方式

#!/bin/bash
set -e
WRAP="${SRCROOT}/scripts/wrap-binaries-as-frameworks.sh"
if [ ! -f "$WRAP" ]; then
echo "error: wrap-binaries-as-frameworks.sh not found at $WRAP"
exit 1
fi

if [ -f "$WRAP" ]; then
bash "$WRAP"

3. 修复所有生成的 .framework 的 CFBundleIdentifier

APP_BUNDLE_ID="${PRODUCT_BUNDLE_IDENTIFIER}" # 从 Xcode 环境自动获取
FRAMEWORKS_DIR="${BUILT_PRODUCTS_DIR}/${FRAMEWORKS_FOLDER_PATH}"
find "$FRAMEWORKS_DIR" -name ".framework" -type d | while read fw; do
plist="$fw/Info.plist"

# 只修改由 wrap 脚本生成的标识符（包含 ai.codebench.pythonext）

fw_name=$(basename "$fw" .framework)
new_id="${APP_BUNDLE_ID}.pythonext.${fw_name}"
/usr/libexec/PlistBuddy -c "Set :CFBundleIdentifier $new_id" "$plist"
echo "Fixed CFBundleIdentifier for $fw: $old_id -> $new_id"
# 重新签名（因为修改了 plist）
codesign --force --sign "${EXPANDED_CODE_SIGN_IDENTITY:--}" "$fw"

Thanks for the detailed repro and screenshots again — they pinpoint it exactly. All three rejection codes are the same root cause, and it was a real gap in the script I pointed you to. Apologies — that one's on me.

Root cause: MH_BUNDLE vs MH_DYLIB. Python .so extension modules are Mach-O type MH_BUNDLE (filetype 0x8, dlopen-only). Apple's validator rejects any .framework whose executable is MH_BUNDLE:

• 90124 — "has type 'BUNDLE'… Only 'EXECUTE' is permitted" → must be MH_DYLIB
• 90210 — "missing load commands" → MH_BUNDLE has no LC_ID_DYLIB
• 90171 — "standalone library… not permitted" → the malformed (non-dylib) binary

wrap-binaries-as-frameworks.sh wrapped your .so into .frameworks but didn't flip the Mach-O type — its install_name_tool -id silently no-ops on an MH_BUNDLE, so they shipped as BUNDLE. The repo already had the fixer (scripts/appstore/fix-macho-type.py), but the wrap script wasn't calling it. Fixed now (commit 321213f5) — the wrap script runs the flip automatically before re-signing.

To unblock you today, either is enough:

Option A — pull the updated script (scripts/appstore/wrap-binaries-as-frameworks.sh, now self-contained; keep fix-macho-type.py beside it), then re-archive.

Option B — add one Run Script phase right after your wrap phase (and before Xcode's code-sign):

python3 "${SRCROOT}/scripts/appstore/fix-macho-type.py" "${BUILT_PRODUCTS_DIR}/${CONTENTS_FOLDER_PATH}"

Verify before archiving — this should print DYLIB, not BUNDLE:

otool -hv "$BUILT_PRODUCTS_DIR/.../Frameworks/scipy-optimize-minpack.framework/scipy-optimize-minpack" | grep -A1 filetype

A few more notes:

• Order matters with your custom CFBundleIdentifier step: run wrap → fix-macho-type → your plist fix + codesign. The type-flip mutates the binary, so it must precede the final signature.
• Don't run both wrap-loose-dylibs.sh and wrap-binaries-as-frameworks.sh. For a SwiftPM app use only wrap-binaries-as-frameworks.sh.
• Import hook: install it after Py_Initialize() and before the first import numpy, with PYTHON_IOS_LIB_HOOK_DIR pointing at your bundled python-stdlib. If it still fails, paste the exact traceback and I'll look.

If an archive still gets a code after the type-flip, send the otool -hv of the offending framework binary and I'll pinpoint it.

你好，非常感谢你的耐心解答和指导，经过反复的尝试我已经将应用打包到商店并成功提交审核，这个过程还是有许多细节问题，后面我会总结一下反馈给你，但是我也收到一个新的商店反馈问题。由于时间我还没有看你的readme文档是否有该解决方案，图片中拒绝APP上架的原因
