chuyển đổi một chuỗi Python thành float chỉ thất bại với PyInstaller

Question

Tôi có một chương trình hoạt động tốt, nhưng khi tôi biến nó thành một tệp thực thi qua PyInstaller, tôi có vấn đề. Tôi truy tìm điều này xuống một hành vi kỳ lạ thể hiện vấn đề. Trong main(), tôi đặt câu lệnh sau:

print float('1e-07') 

Khi tôi chạy script Python bình thường của tôi, nó in '1e-07' như mong đợi.

Khi tôi chạy chương trình PyInstaller.exe của mình, nó sẽ in 'ERR'.

Có ai biết tại sao điều này xảy ra không?

LƯU Ý: Đây không phải là một số vấn đề bí truyền mà tôi đã tạo. Tôi có một ứng dụng khá lớn thường xuyên chuyển đổi chuỗi thành phao. Tôi thấy rằng đọc trong các dự án đã tạo trước đó không hoạt động nữa và tôi đã quản lý để gỡ lỗi này xuống hiệu ứng này. Tôi nên lưu ý rằng đôi khi nó chuyển đổi các con số đúng (trong chương trình của tôi) và đôi khi không. Mọi thứ khác chạy tốt trong ứng dụng - nó chỉ là vấn đề chuyển đổi số. Mọi người đã trả lời bằng nhiều cách khác nhau để chuyển đổi các con số không hoạt động tốt hơn. Mọi câu trả lời nên tập trung vào lý do tại sao một cái gì đó đơn giản như vậy trong Python không hoạt động khi ứng dụng được tạo bằng pyinstaller. Hiện tại, tôi không thể xây dựng bản phát hành phần mềm này cho đến khi tôi có thể khắc phục sự cố này!

UPDATE: Bây giờ tôi đã tạo ra một chương trình bao gồm duy nhất của một dòng in giá trị này và nó in như 'ERR' trong Pyinstaller mã được tạo - phải là một vấn đề PyInstaller hoặc một sự thất bại của tôi để bao gồm một thư viện hoặc một cái gì đó . Bất kỳ trợ giúp sẽ được đánh giá cao.

Các tập tin trông như thế này:

def main(): 
    print float('1e-07') 

if __name__ == '__main__': 
    main()  

Cập nhật lần nữa:

Dựa trên khuyến nghị trong ý kiến, mã của tôi bây giờ trông như thế này:

import traceback 
import sys 

print "test" 
try: 
    print float("1e-07") 
except: 
    traceback.print_exc(file=sys.stdout) 

Không có ngoại lệ được ném và mã chỉ in 'ERR' - nhớ bạn đây chỉ là trong PyInstaller tạo ra tập tin .exe - khi chạy từ PyScripter nó thực hiện tốt.

Output từ PyScripter:
kiểm tra
1e-07

Output từ PyInstaller tạo .exe:
kiểm tra
ERR

Answer 1

Whew! Sau khi tất cả các buổi sáng dành cho việc này, vấn đề đã được tìm thấy.

Điều này được truy nguồn từ một dll - python27.dll.

Tôi đã xây dựng ứng dụng trên máy của bạn bè (từ 2.7.10) và sao chép dll này lên trên bản dựng pyinstaller của tôi, thay thế dll của tôi (từ 2.7.3) và bây giờ mọi thứ đã hoạt động.

Tôi đã thử sao chép nhiều tệp .dll đáng ngờ khác, nhưng sao chép tệp này và chỉ dll này khắc phục được sự cố.

Sau đó tôi cập nhật toàn bộ cài đặt python của tôi lên 2.7.11 - chương trình thử nghiệm mới nhất và được xây dựng và cuối cùng nó in ra 1e-07 như mong muốn.

Sau đó, sau khi xử lý tất cả các sự cố mới mà tôi đã tạo bằng cách cập nhật tất cả điều này (bao gồm pyinstaller), tôi có thể xây dựng ứng dụng bản phát hành của mình.

Thật đáng kinh ngạc và ngạc nhiên khi dường như Python 2.7.3 có vấn đề này với PyInstaller tạo ra các tệp thi hành độc lập, nhưng điều đó có vẻ như vậy.

Answer 2

Mặc dù tôi không thể trả lời tại sao điều này xảy ra, eval ('1e-07') giải quyết được vấn đề.

Mã sau hoạt động tốt.

eval('1e-07') 
print type(eval('1e-07')) 

Mã trên đánh giá nổi.
